Are Stuffed Peppers Keto?

While some stuffed peppers may be keto friendly, it depends on what the stuffing contains. Some recipes call for rice or other grains that would increase the carb count, so always check ingredients to be certain. Luckily, it’s easy to make stuffed bell peppers keto with the right fillings!

Ingredients & Substitutions

This section explains how to choose the best ingredients for keto stuffed peppers, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

Olive Oil – I use extra virgin olive oil for classic Italian flavor in these stuffed keto peppers, but you can substitute any neutral cooking oil.
Garlic – It tastes best freshly minced (especially with the 4 cloves garlic needed here!), but you can use jarred minced garlic to save time. You can also saute diced onions with the garlic if you like.
Ground Beef – It’s the classic meat choice for this keto stuffed peppers recipe, but you could easily substitute ground chicken, ground turkey, or even ground Italian sausage with casings removed.
Bell Peppers – Use your favorite color! Just make sure they’re full size peppers and not mini sized.
Marinara Sauce – Find a keto friendly marinara tomato sauce at the store, or make your own sugar free marinara sauce in minutes.
Italian Seasoning – Use a store-bought mix or make Italian seasoning mix fresh!
Cheese – A combination of ricotta cheese and mozzarella cheese — the classic choices for any lasagna. Although not as traditional, you could easily substitute other keto cheese options such as cheddar cheese or parmesan cheese.

How To Make Keto Stuffed Peppers

This section shows how to make low carb stuffed peppers, with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.

Make meat sauce. Heat oil in a large skillet over medium-high heat. Add garlic and cook until fragrant, followed immediately by ground beef. Cook beef, breaking apart with a spoon, until browned. Add marinara, Italian seasoning, and salt and pepper to taste. Simmer.

Prep peppers. Remove tops of the bell peppers with a sharp paring knife and scoop out seeds and ribs. Place in a rectangular baking dish.

TIP: Got wobbly peppers?

If peppers fall when you stand them upright, slice a tiny portion off the bottom to make a flat space to stand on. Be careful not to cut a hole in the bottom.

Assemble. Stuff peppers with 1/4 cup meat mixture, 2 tablespoons ricotta, and 2 tablespoons mozzarella. Repeat until peppers are filled, finishing with mozzarella as the top layer.

Tent. Tent foil over the baking dish, making sure it does not touch the cheese on the keto stuffed peppers.
Bake. Bake the stuffed pepper recipe for 30 minutes. Remove the foil and continue baking until the peppers are tender and cheese is browned. If desired, place under the broiler for a couple of minutes to brown the cheese more. You can garnish with fresh parsley, basil leaves, or both.

Filling Variations

Low carb stuffed peppers can be so versatile! You can fill them with just about anything. Here are some other combinations to try:

Mediterranean – Use ground lamb or turkey as your base meat, and season it with Mediterranean spices like oregano, cumin, and coriander. Fill the peppers with a mixture of sautéed spinach, feta cheese, and diced tomatoes (or sun-dried tomatoes).
Mexican – Opt for ground pork (seasoned with 3 tablespoons of either store-bought or homemade taco seasoning) or chorizo. Fill peppers with a blend of cauliflower rice, diced tomatoes, and shredded cheddar cheese. You can also make my turkey taco stuffed peppers or fajita-inspired chicken stuffed peppers instead.
Pizza – Stick with ground beef mixed with keto marinara sauce or keto pizza sauce. Layer the peppers with pepperoni slices, diced bell peppers, the beef mixture, and shredded mozzarella cheese. See my pizza bowls for more ideas.

Storage Instructions

Store: Cover keto lasagna stuffed peppers and store 3-4 days.
Meal prep: Cook meat sauce ahead of time and store until ready to assemble. Alternatively, make the full stuffed peppers low carb recipe and store until ready to reheat and eat.
Reheat: Warm in the microwave at low power, or in the oven at 350 degrees F, until heated through.
Freeze: Wrap the baked low carb stuffed bell peppers individually to freeze, or wrap the full casserole container and store in the freezer for 2-3 months. Reheat in a 350 degree F oven, until hot. It’s best to freeze after baking rather than before; I don’t recommend freezing raw peppers.
