The frozen aisle has long had a reputation for featuring less-than-nutritious food. Today, this is far from true—many options in the frozen section are full of nutrients and aretypically more budget-friendly. You also can save time on prep, all while reducing food waste.
So when you’re managing your blood sugar levels, you can go ahead and turn your cart down the frozen aisle. The key here is identifying the freezer staples that help balance blood glucose. With the help of registered dietitians, here’s what we found.
The 10 Best Frozen Foods for Blood Sugar
1. Frozen Broccoli
Frozen veggies and fruits are generally harvested at peak ripeness, and then they are blanched or flash-frozen to preserve their quality, flavor and nutrients.
We love frozenbroccolibecause it is pre-cut, slashing prep time. As a versatile veggie, broccoli is full of nutrients and fiber, with every cup of cooked frozen broccoli providing more than 5 grams of fiber.Plus, broccoli contains sulforaphane, a sulfur-containing compound that gives the veggie its distinct aroma and bitterness, and which may help manage blood sugar and insulin resistance.
2. Frozen Spinach
We love using frozen spinach forside dishes. Since Popeye’s favorite veggie shrinks substantially when cooked, you can easily eat more of it in a sitting compared to fresh spinach. And that means you’ll consume more nutrients. In fact, 1 cup of cooked frozen spinach has 8 grams of fiber, compared to less than half a gram for a cup of raw spinach.
Add frozen spinach to soups,stews,fritters,quiches, dips and more—check out our12 recipes featuring a bag of frozen spinach.
3. Frozen Kale
Kale is another leafy green that freezes well and has an impressive nutritional profile. One cup of cooked frozen kale has almost 4 grams of fiber.Plus, kale contains quercetin and kaempferol, antioxidants that may help lower blood sugar and improve insulin sensitivity.
Use frozen kale to make soups, like ourChorizo, Potato & Kale Soup,or add a handful to smoothies like ourReally Green Smoothie.
4. Frozen Corn
Cornis a perfect side dish because it is both a whole grain and a vegetable. When eaten in moderation, corn kernels are also a low- to moderate-glycemic food, meaning they are less likely to induce sudden spikes in blood sugar.You may be surprised that 1 cup of cooked frozen corn has 4 grams of fiber, making it an excellent grain choice to accompany alean proteinof choice.OurSkillet Cornrecipe makes a tasty and sweet side in 20 minutes.
5. Frozen Cauliflower Rice
Cauliflower rice is a great alternative to grains if you are keeping an eye on your blood sugar. Each 3-ounce portion of uncooked cauliflower has 2 grams of fiber and 4 grams of carbs.While you can make your own cauliflower rice from scratch, a frozen bag from the store cuts down on prep time if you are in a hurry. These17 recipe ideaswith cauliflower rice can inspire you to make deliciouspilafs, fried “rice,“casseroles,burrito bowlsand many more.
6. Frozen Berries
Frozen berries—blueberries, raspberries, strawberries, blackberries and mixed berries—are picked and frozen when they are most ripe. Berries are excellent for managing blood sugar because of their fiber content, offering, on average, 3 grams of fiber for every cup.Thaw berries as a topping forMulti-Grain Wafflesor toss into smoothies,nice cream, yogurt and oatmeal.
7. Frozen Avocado
Avocados are packed with unsaturated fats that promote heart health. They are also an excellent fruit because they have little impact on blood sugar levels—1/2 cup of frozen avocado has 4 grams of fiber.
The downside of fresh whole avocados is that they don’t last very long at room temperature before they turn soft and brown. Frozen is a perfect alternative if you would like to cut down on food waste while offering the same delicious taste in your recipes, especially when it comes tosmoothies.
8. Frozen Fish
Protein helps slow digestion and blunts carb and sugar absorption, stabilizing blood sugar levels. Lean options like fish are excellent to include in a balanced meal pattern.
Specifically, plain frozen fish likesalmonand cod are full of nutrients. They are also a source of omega-3 fats, and 3 ounces of cooked salmon and cod contain 21 and 17 grams of protein, respectively.Not only that, many frozen fillets are pre-portioned and quick to thaw, saving on meal prep time.

10. Frozen Shelled Edamame
This plant-based protein is an excellent source of protein and fiber, boasting 18 grams of protein and 8 grams of fiber per cup.Edamame also has a relatively low glycemic load due to its high fiber and protein content, making it an ideal plant-based protein that won’t drastically raise blood sugar levels.
