How to Make This Keto Stuffed Bell Peppers, Step-by-Step
Now, let’s get to the fun part—cooking! Making these stuffed peppers is a straightforward process, and I promise you’ll be amazed at how easy it is.
Step 1: Prep Peppers: Start by preheating your oven to 350°F. While that’s warming up, wash your bell peppers. Slice them in half, remove the seeds and membranes, and place them cut side up in a baking dish. Give them a light seasoning of salt and pepper to enhance their natural flavors.
Step 2: Cook Filling: In a skillet over medium heat, brown your ground beef until it’s fully cooked. Make sure to drain any excess grease and set the beef aside. In the same pan, add a pad of butter and sauté your diced onions, riced cauliflower, and minced garlic until they’re tender and fragrant—about 4-5 minutes.
Step 3: Combine Ingredients: Now, let’s bring everything together! Add the cooked beef back to the pan along with the marinara sauce, dried basil, garlic salt, and black pepper. Stir everything until it’s heated through and well combined.
Step 4: Stuff & Bake: Spoon the delicious filling into each bell pepper half, packing it in generously. Top each pepper with a sprinkle of shredded cheese. Cover the baking dish with foil and pop it in the oven for about 30 minutes.
Step 5: Serve: After 30 minutes, remove the foil and take a moment to enjoy the aroma wafting through your kitchen. Let them cool for a minute, then serve hot and enjoy!

Pro Tips for the Best Results
Here are a few pro tips to ensure your stuffed peppers turn out perfectly every time:
- Feel free to experiment with different proteins! Ground turkey, chicken, or even a meat alternative will work beautifully in this recipe.
- If you like a bit of heat, add some diced jalapeños or red pepper flakes to the filling for a spicy kick.
- Want to add more veggies? Chopped spinach or zucchini can be mixed into the filling for added nutrition and flavor.
Serving Suggestions
These stuffed peppers are fantastic on their own, but if you want to elevate your meal, consider serving them with a side salad or some steamed broccoli. A dollop of sour cream or guacamole on top can add a creamy contrast that’s simply delightful. You can even serve them with a side of cauliflower rice for a complete low-carb feast!
Storage and Make-Ahead Tips
These Keto Stuffed Bell Peppers are perfect for meal prep! Once they’re baked, you can store any leftovers in an airtight container in the fridge for up to 4-5 days. If you want to make them ahead of time, you can assemble the stuffed peppers and store them unbaked in the fridge for up to a day. Just pop them in the oven when you’re ready to enjoy! You can also freeze them before baking; just thaw in the fridge overnight before cooking.
Cooking should be a joyful experience, and I hope this recipe inspires you to get creative in your own kitchen. Remember, it’s all about simple food, real ingredients, and no pressure. Happy cooking!
