Easy Potato Hack To Lower Glycemic Index (Cook, Chill, Reheat Method for Guilt-Free Carbs)

russet potatoes aka idaho potatos

Potatoes sometimes get unfairly dragged into the “bad carb” conversation, but for active people, athletes, and anyone who trains regularly, they can actually be one of the best whole-food fuel sources around. They’re affordable, versatile, naturally gluten-free, and packed with nutrients that support performance and recovery. Even better, there’s a simple kitchen trick that can make potatoes more blood-sugar friendly and more filling without sacrificing flavor.

The Simple Potato Trick

To lower the glycemic impact of potatoes and increase satiety, try this easy three-step process:

  1. Cook the potatoes (boil, bake, roast, steam — any method works)
  2. Chill them in the refrigerator for 12–24 hours
  3. Reheat and enjoy

When cooked potatoes cool, some of their starch changes into something called resistant starch. Resistant starch behaves more like dietary fiber in the body. It isn’t digested as quickly in the small intestine, which means:

  • Slower glucose release
  • Less dramatic blood sugar spikes
  • Longer-lasting fullness

Research suggests that this cooling process can reduce the glycemic impact of potatoes by roughly 25–40%. Translation: better sustained energy and fewer spikes and crashes.

Even better — reheating the potatoes doesn’t destroy the resistant starch, so you can still enjoy them warm in many of your favorite dishes.

Why Potatoes Are Great Fuel for an Active Lifestyle

Potatoes are a healthy source of energy-providing carbs for the athlete.

For athletes, runners, and anyone who trains regularly, potatoes check a lot of nutritional boxes.

1. High-quality carbohydrates for energy
Carbohydrates are your body’s preferred fuel for exercise, especially endurance training and high-intensity workouts. Potatoes provide easily accessible carbs that help replenish glycogen stores after training.

2. Potassium powerhouse
One potato contains more potassium than a banana, ounce for ounce. Potassium plays a key role in muscle contraction, hydration, and nerve function, all essential for active people.

3. Naturally fat-free and whole-food based
Potatoes are a simple, minimally processed carbohydrate source that pairs well with protein and healthy fats to create balanced meals.

4. Surprisingly filling
Potatoes rank very high on the satiety index, meaning they help keep you satisfied longer compared to many other carb sources. The resistant starch trick can boost that effect even more.

This Potato Hack Works with Variety

The cooling method works with all varieties of potatoes. So whether you’re meal prepping roasted potatoes, boiling them for potato salad, or baking a batch for the week, the cook → chill → reheat method still works.

  • Russet
  • Yukon Gold
  • Red potatoes
  • Baby potatoes
  • Purple potatoes
  • Sweet potatoes (which also contain resistant starch when cooled)

How to Use Chilled Potatoes in Everyday Cooking

Once your potatoes have been chilled for 12–24 hours, you can use them in almost any recipe that calls for a softer cooked potato. Here are a few easy ideas:

Mashed potatoes
Bake or boil potatoes, chill overnight, then reheat and mash with your favorite add-ins.

Baked potatoes
Bake ahead, refrigerate, then reheat the next day for a quick meal prep side.

Roasted potatoes
Cook and chill whole potatoes, then cube and roast the next day for crispy edges.

Soups and stews
This is one of my favorite tricks. I often make my entire pot of soup with the potatoes boiled in, then chill overnight before eating. It still delivers the resistant starch benefits even though cooked alongside the other ingredients.

Notes About Raw Potato Storage

One important tip: don’t refrigerate raw potatoes before cooking them. The FDA and potato industry guidelines recommend storing raw potatoes in a cool, dark, well-ventilated place rather than the refrigerator.

The reasoning for not chilling raw potatoes is that when they are stored in cold temperatures, some of their starch converts to sugar. When those potatoes are later cooked at high temperatures, the extra sugar can contribute to the formation of acrylamide, a compound that researchers monito because it may pose carcinogenic health risks in very high amounts.

But, refrigerating potatoes after they’ve been cooked, however, is perfectly safe and is exactly what creates the resistant starch benefit. 

Here are a few recipe ideas that start with chilled potatoes:

Pro Tip #1: If you don’t have a spiralizer (I love my spiralizer attachment for the Kitchenaid Mixer), a similar result can be achieved with an inexpensive manual spiralizer, shredding potatoes with a food processor, or grating with a simple box grater. That last box grater option will give you an arm workout too!

Pro Tip #2: After spiralizing or grating, rinse off potatoes in a bowl of cold water to remove the excess starches. You can skip this step, but the potatoes will be gloppy and less crispy (but still taste just fine).

Pro Tip #3: Line the baking sheet with a silicone baking sheet or parchment paper. This recipe will stick to pan otherwise.

Pro Tip #4: You can adjust the chili spice level up or down depending on the preference of your family.

Pro Tip #5: Use an approximate 10” x 15” rimmed baking sheet and don’t overfill it.  Use the amount of potatoes called for in the spiralized potato recipe. Too many spiralized potato strands and the hash browns will not bake up crispy.

Pro Tip #6: Don’t try to flip or stir the potatoes during baking. They WILL get crispy on top and bottom and lining the pan with parchment will keep them from sticking.  

Pro Tip #7: Sheet pan potato recipes like these spiralized chili lime hash browns are very versatile and work for breakfast, brunch, lunch and dinner!

Reduce food waste by roasting the “potato butts” that are remnants after spiralizing. They look so funny, but taste just as yummy!

The inspiration for this super easy recipe is “colcannon,” a traditional Irish dish made from creamy mashed potatoes and kale or cabbage. Potatoes and Irish culture or forever linked, as we all learned in history class – at one point leading up to the mid-17th century Great Potato Famin, it was said that the average Irish laborer ate 10 pounds of potatoes a day and for three-fifths of the population it was the primary fuel of life.

Okay, eating such a potato-centric diet causes dietary imbalances, but potatoes ARE a smart choice as a side dish to protein and other fruits and vegetables in your healthy diet. Tubers are packed with wholesome nutrients including complex carbohydrates for quality energy and vitamins and minerals, especially iron, magnesium, vitamin B-6 and vitamin C.Kale Pesto Oven Fries an be spiralized or cut into wedges for a quick and easy potato side dish.

It’s no blarney, you are guaranteed to love my Kale Pesto Potato Fries Two Ways with Blue Cheese Sauce  — just remember not to call them French fries, Irish fries is more fitting! The kale pesto is a snap to make in the food processor, and can easily be done while the potatoes are baking in the oven. Make  another batch or use leftovers on pasta, fish, chicken, pizza and more. BTW, the pesto is nut-free so everyone can enjoy!Spiral Cut Potatoes

As for prepping the potatoes – you can use a spiralizer, a mandolin, finely julienne by hand or cut into fatter wedges, it’s the cook’s choice! I’ve used tried-and-true Russet potatoes in this dish, you could use whatever variety potato you like – on super busy days, I’ve also even hacked the recipe with frozen shoestring potatoes.

5 Ways to Get Teens’ Taste Buds to Grow Up + Visa GC Giveaway

Even though my family eats (mostly) a healthy diet, I’ve been encouraging my teenagers to break their monotonous meal preferences and try new dishes with exciting flavors. As they move through high school and college there are so many diverse and cultural eating experiences that will be missed (along with a wider array of nutrients) if they are dead set on having turkey meatballs, plain brown rice and an undressed salad for dinner (an all-too-common menu). That’s why I was excited to hear how Birds Eye Veggies is on a mission to redefine the way we all eat our vegetables with their Birds Eye® Flavor Full line of bold and exciting veggies that can be enjoyed as a side dish or the main course!  Keep reading down to the end of the post for the Gift Card Giveaway.

Birds Eye Flavor Full Veggies - Buffalo Cauliflower

This got me to thinking. Can picky eating-children change, or do they just grow up into adults who are ultra finicky about their food? There are valid reasons why a young child may avoid certain foods at all costs — did someone say “temper tantrum”?!  Factors that contribute to a picky eater include all the legitimate sensory things you’d connect with food aversions like texture, temperature, taste and flavor. Picky eating is also encouraged by parental response as well as peer pressure when kids get a little older. Allergies, too, can play a welcomed defensive role in picky eating, a way your body tells you to say away from a certain harmful food – but I won’t get into that here.

I believe that with the right opportunities and encouragement, most kids can join the adult world of eating as they move into their ‘tween, teens and early twenties. One reason is that as we age, taste buds dwindle away from an average of 10,000 working taste buds in small kids to only 5,000 in adults – simply put, things start tasting less intense and we naturally seek out more flavor. To support this, a 2005 study published in the Pediatrics journal reports that most children do not like bitter tastes (often found in vegetables), while adults do not find offense.

Always funny or philosophical, this kiddo says “Potatoes are the ‘gateway’ vegetable”

Another interesting study conducted in 2012 at the University of Copenhagen reported that when children move into their teens, they have a decreased interest in sugary tastes and a higher sophistication to distinguish between tastes – however, they are often more resistant to trying new foods than toddlers! This is why, we as parents, need to set a good example by eating a balanced diet filled with a variety of colorful, nutrient-dense whole foods.

Here are some tips to encourage the teenagers in your family to become veggie lovers and also try out other exciting new flavors. Of course, if your teen is not eating because of control issues, an eating disorder, real or perceived allergies or other concerning reasons, please see a medical professional as soon as possible.

5 ways to get your teen's taste buds grown up

  • Get teens cooking: Not only does teaching your older children how to prepare meals create self-sufficiency; it also creates a more adventurous attitude about eating as they master various skills.
  • Host international night: Once a month, prepare a meal that features cuisine from a different culture – for example, Indian, Korean, Thai, or Italian (no pizza!). To keep everyone happy, every family member gets to select one recipe to be included on the menu, but has to eat at least three bites of every other dish. Have them invite a friend over who may just announce “ooh, I love curry” – and suddenly your son or daughter will too!
  • Focus on vegetable variety: As teens lose their taste for sugar (allegedly it’s a real thing!), support their savory side with more and more vegetables. Look past buttered green beans and toward more exotic or bold tastes, like Buffalo Cauliflower! Filling up your plate with a rainbow of vegetables is the easiest and tastiest way to optimize health, in my opinion.
  • Educate and relate: Share online resources for healthy and clean eating with your children. Older kids are smart enough to understand that eating vegetables and a variety of foods is best, but are sneaky when it comes to actually eating what you serve – just think of all the Brussels sprouts “dropped” on the floor or yogurt and berry parfaits swapped for pink cupcakes at lunch. I always share the story of how I traded my celery, peanut butter and raisin “ants on a log” for Ding Dongs at lunch and quickly lost my get-up-and-go for gymnastics practice in the afternoon.
  • Role model without pushing: No one likes a pea pusher, and even worse so if it’s your own mother or father. With most teens, realize that the more you “strongly suggest” you eat your vegetables or try new dishes, the more likely they are to rebel by absolutely doing the opposite. They are teens, they will come around – just keep the message honest yet low-key, the most important thing you can do is be a role model for clean eating.
