8 Frozen Foods That Make My Life Easier as a Dietitian

by Hannah Poplin RD, LDN on

As a dietitian and someone who's constantly staying busy, I make sure my house always has one thing: frozen foods!

Frozen foods aren't just convenient; they can be a real lifesaver for hectic days. And while there's a lot of talk about "ultra-processed" foods, there are plenty of frozen staple items that provide great nutritional value and make family meals easier, more affordable, and much less stressful!

Explore why frozen foods are a great kitchen staple and my top picks to keep on hand.

The Benefits of Buying Frozen Foods 

  • Longer Shelf Life

Frozen foods don’t play the expiration date guessing game. They last months, sometimes years, without losing quality (ideal for unpredictable weeks or last-minute meals.) Stock up on spinach, berries, or shrimp without stressing about waste.

  • Nutrient Retention

Freezing preserves nutrients better than you might think. Produce is typically harvested at peak freshness and frozen within 24 hours, locking in vitamins like C and antioxidants that degrade in fresh items during transport or storage. Frozen broccoli, for instance, often retains more riboflavin than its fridge-bound counterpart.

  • Convenience

Items like frozen pre-chopped veggies, pre-cooked grains, and individually portioned fish fillets cut prep time to near zero. They’re the best backup plan for nights when cooking feels like a chore.

  • Budget-Friendly

Frozen foods often cost less than fresh, particularly for out-of-season produce or premium proteins like wild salmon. Additionally, buying in bulk stretches grocery budgets further.


Now, let's talk about my go-to frozen foods and why I keep my freezer stocked with them:

8 Freezer Staples Every Busy Household Needs

1. Frozen Vegetables

Frozen veggies are a lifesaver, especially microwavable steamer veggies. They’re easy, quick, and retain their nutrients because they’re flash-frozen at peak freshness. Plus, they save time and energy when you need to add more veggies to a meal without any prep work!

You can quickly toss frozen veggies like spinach or cauliflower into soup, pasta, stir fry, and even smoothies. With so many options, frozen veggies are a simple way to make meals more nutritious without the hassle.

My Favorite Options:

2. Frozen Fruit

Frozen berries, mango, and pineapple are perfect for smoothies, yogurt parfaits, or oatmeal. Picked and frozen at peak ripeness, they lock in vitamins and antioxidants.

No chopping, no spoilage, just effortless nutrition that’s often fresher than what’s sitting in your fridge. Best part? They’ll wait patiently in your freezer until you need them (no more forgotten fruit turning to mush in the fridge!)

My Favorite Options:

  • Frozen avocado – great to add to smoothies or thaw and use for avocado toast or guacamole.
  • Frozen mixed fruit – an easy option for smoothies without all the chopping.
  • Frozen cherries – fresh tend to be a bit pricy, but you can find frozen cherries for a reasonable price that have already been pitted!

3. Frozen Grains

Pre-cooked rice and quinoa save so much time on busy nights. They're a great base for stir-fries, grain bowls, or quick side dishes. No waiting around for water to boil, just heat and serve! Plus, some options are lightly seasoned or pre-mixed with veggies, making them a great way to try new food combinations without the extra prep, longer list of ingredients, or potentially wasted fresh produce.

My Favorite Options:

4. Frozen Pancakes and Waffles

Mornings get busy too! Look for frozen breakfast options that are whole grain for more fiber (even if they're not, that's ok too.) Top frozen waffles with peanut butter, yogurt, or fruit for additional nutrients. They're also great for a quick snack, plus who doesn't love the occasional breakfast for dinner?

My Favorite Options:

5. Premade Meals

Even dietitians have days when they don't have the time (or the want) to cook. So for those days, I keep some premade meals on hand. Now, not all premade freezer meals are equal. I grab ones with at least 15g protein, 5g fiber, and under 600mg sodium. Flash-freezing locks in nutrients better than my leftovers ever could. Sometimes they might bake for 40 minutes—but that’s hands-off time I’ll gladly trade for playing with my pets or finally tackling the dishes.
Toss a fresh veggie on the side or add a quick salad, and boom: a balanced meal you don't have to feel bad about. Again, convenience doesn’t have to mean compromise.

My Favorite Options:

6. Chicken

Whether it's nuggets, tenders, or pre-grilled strips, I always have some frozen chicken in my fridge. They make for an easy protein option that you can cook up quickly and easily pair with fruit or a vegetable and whole grains to make a balanced meal. Bonus: they're also great for making DIY wraps, salads, or quick bento box lunches!

My Favorite Options:

7. Frozen Desserts

Because balance! A little frozen treat can bring some joy to the end of a busy day. It gives you a chance to slow down and (literally) savor the moment. Plus, it's a great reminder that part of having a healthy relationship with food is knowing you can still enjoy the foods you love in moderation!

My Favorite Options:

8. Frozen Pizza

Frozen pizza is a go-to for busy weeknights. Quick, easy, and always a hit! Add extra veggies like spinach, peppers, or mushrooms, or pair it with a salad, and you've got a balanced meal in minutes. Plus, it's perfect for a fun movie night in on a Friday after work!

My Favorite Options:

Balancing Fresh vs Frozen

Instead of fearing foods that you didn't make yourself, think about how you can create a balanced meal. Yes, most frozen foods are some level of processed (some more than others), but this doesn't make them 'bad' or unhealthy. Here's the mindset I have when walking to the frozen aisle:

  • Prioritize Nutrient-Rich Choices: Choose frozen fruits, vegetables, and lean proteins that you can use to build balanced meals. Focus on options that fuel your body with vitamins, fiber, and protein.
  • Combine with Fresh or Whole Ingredients: You can easily level up frozen meals by pairing them with leafy greens, whole grains, or legumes for added texture, flavor, and nutrition.
  • Embrace Flexibility and Variety: It's ok to have convenient frozen staples on hand, but rotate them out with seasonal produce, whole foods, and proteins to keep a balanced diet.
  • Think Long-Term, Not Perfection: Remember, this is just one meal. Progress thrives on consistency, not flawless choices. Focus on overall patterns, like mindful eating or staying active, instead of fixating on individual meals.

Takeaways

Frozen foods are a game-changer when you're schedule's packed, and they're not something to fear. The truth is, many of them are frozen at the peak of freshness and can provide just as many nutrients as their fresh counterparts. When you use them thoughtfully, they actually make it easier to make nutritious meals!

Plus, they save time, reduce food waste, and are budget-friendly. So, whether it's throwing them into a veggie-packed stir-fry or pairing a frozen pizza with a salad, there's no need to stress - you've got this!
