A Dietitian’s Go-To Unstuffed Pepper Skillet Recipe

If you’re looking for a recipe that’s fast, healthy, and genuinely satisfying, you’ve found it.

As a Registered Dietitian, I’m constantly asked for easy weeknight dinner ideas that don’t sacrifice nutrition for convenience.

This Unstuffed Pepper Skillet is one of my top recommendations.

We’re taking all the beloved flavors of classic stuffed peppers—the savory meat, the sweet peppers, the rich tomato sauce—and making it incredibly simple by cooking it all in one pan.

It’s a perfectly balanced meal that delivers on taste while saving you a sink full of dishes.

What Makes These Unstuffed Peppers So Good For You?

Many of us grew up with classic stuffed peppers, but from a nutritional standpoint, this deconstructed version is often a smarter choice for a regular meal.

Here’s why I recommend it to my clients: A Truly Balanced Meal: Each serving is designed to be nutritionally complete.

You get lean protein from the ground turkey (around 36 grams per serving), which is essential for muscle maintenance and satiety.

The rice provides energizing carbohydrates, and the abundance of bell peppers, onions, and tomatoes delivers crucial fiber and vitamins.

Research consistently shows that balanced meals like this help regulate blood sugar and keep you feeling full longer.

Packed with Fiber and Nutrients: We use a whole head of cauliflower rice in addition to regular rice.

This is a technique I call ‘volume building,’ as it dramatically increases the meal’s fiber and nutrient content without significantly increasing the calories.

With over 7 grams of fiber per serving, this dish strongly supports digestive health, which the Academy of Nutrition and Dietetics notes is critical for overall wellness.

Furthermore, the bell peppers are loaded with Vitamin C, and the cooked tomatoes provide lycopene, a powerful antioxidant studied for its role in cellular health, as highlighted in a 2021 study in Antioxidants.

* Controlled Sodium and Fats: Store-bought sauces and traditional casserole-style dishes can be high in sodium and saturated fat.

By making the sauce from simple canned tomatoes and controlling the amount of cheese, you have complete authority over what goes into your meal.

This aligns with recommendations from the American Heart Association to be mindful of sodium intake for cardiovascular health.

What Are the Main Ingredients in This Skillet?

The magic of this recipe is in its simplicity and the nutritional power of each component.

Here’s a look at the core ingredients and why they were chosen: Ground Turkey: I opt for lean ground turkey (93/7) as it’s a fantastic source of protein while being lower in saturated fat than many cuts of ground beef.

A Rainbow of Bell Peppers: Don’t just stick to one color!

Red, yellow, and orange peppers are used here for their sweet flavor, but they also offer a broader range of phytonutrients than green peppers alone.

This is a simple way to practice the ‘eat the rainbow’ principle recommended by nutrition experts.

Cauliflower & White Rice: We use both for a reason.

The cooked white or brown rice provides that classic, comforting texture and essential carbohydrates for energy.

The frozen riced cauliflower adds bulk and a significant serving of vegetables almost undetectably.

It’s a great way to get picky eaters to consume more veggies.

Canned Tomatoes & Sauce: This duo forms a flavorful, low-sodium base.

Look for diced tomatoes and tomato sauce with no salt added to better control the sodium levels.

* Cheddar Cheese: Is a meal really satisfying without a little indulgence?

The cheese adds a wonderful flavor, a creamy texture, and a bit of calcium.

We’re only using about 1/2 cup for the entire dish, which adds immense enjoyment without compromising the meal’s health benefits.

Ready in 30 Minutes? Let’s Get Cooking

This recipe is designed to be forgiving and fast. You’re basically just layering ingredients in the skillet. Here’s how to do it step-by-step:
1. Brown the Turkey: Heat a tablespoon of olive oil in a large skillet or Dutch oven over medium-high heat. Add the ground turkey and cook, breaking it apart with a spoon, until it’s browned and cooked through. Drain any excess fat if necessary.
2. Sauté the Aromatics: Add the diced onion to the skillet and cook for 3-4 minutes until it begins to soften. Add the minced garlic and cook for another minute until fragrant.
3. Soften the Peppers: Add the chopped bell peppers and cook for about 5 minutes, stirring occasionally, until they start to become tender-crisp.
4. Add Veggies & Grains: Stir in the frozen cauliflower rice and cook for 3-4 minutes until it’s heated through. Then, add the cooked rice, can of diced tomatoes (undrained), tomato sauce, salt, and pepper. Stir everything together until well combined.
5. Simmer and Meld: Bring the mixture to a gentle simmer. Reduce the heat to low, cover the skillet, and let it cook for about 10 minutes. This step is crucial for allowing the flavors to meld together.
6. Melt the Cheese: Uncover, sprinkle the shredded cheddar cheese evenly over the top. Place the lid back on for another 1-2 minutes, or until the cheese is perfectly melted and gooey. Serve immediately, garnished with fresh parsley if desired.

How Do I Store This for Later?

This skillet is a meal prepper’s dream.

The flavors actually get better the next day as they have more time to mingle.

Here’s how to store it safely and effectively: For the Refrigerator: Allow the skillet to cool down for about 20-30 minutes before transferring it to airtight containers.

According to FDA food safety guidelines, you shouldn’t leave it at room temperature for more than two hours.

It will stay fresh and delicious in the fridge for up to 4 days.

For the Freezer: This recipe freezes beautifully.

Portion the cooled mixture into freezer-safe containers or bags.

It can be stored in the freezer for up to 3 months.

To reheat, you can thaw it overnight in the refrigerator and then warm it in the microwave or on the stovetop.

Can I Change Up the Ingredients?

One of the best things about this recipe is its flexibility.

You can easily adjust it to fit your dietary needs or simply use up what you have in the fridge.

Here are a few dietitian-approved swaps: Make it Plant-Based: Swap the ground turkey for a can of rinsed black beans and a can of rinsed lentils.

Add them in step 4 with the rice and tomatoes.

This will also increase the fiber content.

Try a Different Grain: Quinoa is a great substitute for rice and will add a boost of plant-based protein.

Cook it according to package directions before adding it to the skillet.

Add a Little Spice: For those who like heat, add 1/4 teaspoon of red pepper flakes or a finely diced jalapeño with the garlic.

The capsaicin in chili peppers has been studied for its potential metabolism-boosting effects.

Sneak in More Greens: Stir in a few large handfuls of fresh spinach at the very end and let it wilt into the mixture just before you add the cheese.

Conclusion

There you have it—a complete, satisfying meal all cooked in a single pan.

This unstuffed pepper skillet isn’t just about saving time on a busy weeknight; it’s about proving that truly healthy eating can be flavorful, simple, and enjoyable for everyone at the table.
