Flavorful & Filling Stuffed Bell Peppers

If you’ve been with me for a bit, you know I love stuffing my food with other food. My Lasagna Stuffed Mushrooms with Ricotta and Cheese Stuffed Peppers are just a couple of my go-tos! These easy stuffed peppers are my latest fixation. They are great for adding variety to my weekly meal plan while also helping to make sure I get all the nutrients I need. 

I especially love the great combination of ingredients in this recipe. The peppers, onions, garlic, and turmeric build a rich, aromatic layer, while the dried and fresh herbs add a complexity of flavors to the filling. Then, the stuffed peppers hang out in a jacuzzi of tangy tomato sauce until soft, juicy, and bursting with flavor. 

Great for a busy schedule (I can attest!), these high protein stuffed peppers are a meal prep favorite and an effortless way to get food on the table after a long day. Try them out for yourself!

Top Ingredients for Healthy Stuffed Peppers

(Note: These are the recipe’s starring ingredients, but you can find all the ingredients in the recipe card below!)

  • Yellow onions: The best onion for this recipe, as it adds a sweet, savory flavor to the filling.
  • Turmeric: Turmeric is cooked into the beef and the tomato sauce for a deep, warming flavor.
  • Garlic: Creates a deeper, savory flavor that is absolutely essential to this dish.
  • Ground beef: I recommend using lean ground beef for this peppers recipe. I used 85/15 for a good fat content without being too greasy.
  • Dried herbs: I used oregano, mint, tarragon, and savory for this recipe, but feel free to use your favorite dried herbs.
  • Lemon juice: This is added to the beef and sauce for a bright, tangy flavor.
  • Tomato paste: The best way to get a rich, flavorful sauce is to use tomato paste. It’s more concentrated and adds depth to the dish.
  • Tomato sauce: Use a good quality tomato sauce to really enhance the flavors.
  • Fresh herbs: I used basil, parsley, chives, cilantro, and dill for a fresh and aromatic addition to the filling.
  • Red bell peppers: Red bell peppers have a slightly sweeter flavor and hold up well when stuffed and cooked. 
  • Kaizen rice: Adds even more protein and fiber to this healthy dish!

Substitutions & Additions

Filling: Use whatever ground meat you’d like. Ground turkey, ground chicken, or sausage all work well. 

Bell Peppers: You can use orange or yellow bell peppers. Green bell peppers work too, but they’ll have a slighter bitter flavor.

Add Cheese: Mozzarella cheese, cheddar cheese, or any other kind of shredded cheese can be added to the top of the stuffed peppers before baking for a gooey, melty addition.

Add extra veggies: Amp up the veggie power by adding some chopped zucchini, mushrooms, or spinach to the filling. It’s a great way to sneak in more nutrients and add some texture to the dish.

Fun Topping Ideas

I love adding Greek yogurt and any leftover fresh herbs from the recipe to the top of my stuffed peppers for a creamy and tangy element. You could also add your favorite hot sauce, some feta cheese, or sliced avocado on top for added flavor and spice.

STEP 1 – ADD AROMATICS

To start, bring a pan to medium heat, add 1 tablespoon olive oil, 2 yellow diced onions, 3-4 tablespoons water, and saute.

Once onions are translucent, add 2-3 large minced garlic cloves, 1/2 tbsp turmeric, a couple of pinches of salt and pepper, and stir.

STEP 2 – COOK BEEF

Next, add the ground beef and bring the heat to medium-high. Season ground beef with the oregano, mint, tarragon, and dried savory. Continuously mince with a spatula to get rid of any crumbles.

While the meat cooks, you can prepare the Kaizen rice according to the package instructions, if needed. 

Once the meat has browned, squeeze the juice of half a lemon and add the tomato paste and 2/3 can of tomato sauce. Stir for about 2 minutes.

STEP 3 – ADD FRESH HERBS

Grab a large handful (or about 1 cup) of each: fresh basil, fresh parsley, fresh chives, and a smaller handful (1/2 cup) each of fresh cilantro and fresh dill. Roughly chop and add on top of the meat, stirring for another 1 to 2 minutes. Add the Kaizen rice to the mixture. Turn off the heat and set aside.

STEP 4 – MAKE SAUCE

Bring a saucepan to medium heat. Add 1 tbsp olive oil and 1 diced onion. Saute until translucent, then add the garlic, turmeric, 1 can of tomato sauce, 1/2 cup of water, the juice of half a lemon, and a pinch of salt and pepper. Bring to a simmer, then set aside.

STEP 5 – ASSEMBLE & BAKE

Cut the bell peppers about 1/4 inch down from the top and empty the middle using a knife or a spoon. Spoon the meat mixture inside the peppers and place in a large pot. 

Once all the peppers have been put in the pot, pour the sauce from the saucepan around the bell peppers

Put the lid on, and cook on medium heat over the stove for 35-45 minutes.

FAQ

Do I need to boil the peppers before stuffing them?

Nope! You don’t have to worry about the peppers cooking evenly, as the tomato sauce and moisture from inside the pot will gently steam them and help them cook through.

What goes well with stuffed peppers? 

These peppers are a great standalone meal, but you can also serve them with a side of quinoa, brown rice, or cauliflower mash for some added protein and fiber.

I also recommend a side salad like my Mediterranean Cucumber Salad (Salad Shirazi) or another tasty Mediterranean-inspired side like these Air Fryer Mediterranean Vegetables or this Chopped Mediterranean Chicken Salad.

Can I freeze stuffed peppers?

Yes. To freeze them cooked, let them cool completely and then wrap them individually in foil. Thaw overnight in the fridge before reheating.

Storage

Store any leftover stuffed peppers in an airtight container in the fridge for up to 3-4 days. To reheat, place them on a baking dish and heat in the oven at 375°F for about 10-15 minutes.
