Ingredients Needed to Make Low Carb Beef and Pepper Cheesy Bake
- 1 lb ground beef
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- 1 small onion, chopped
- 2 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon Italian seasoning
- 1 cup shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 2 tablespoons olive oil

Instructions to Make Low Carb Beef and Pepper Cheesy Bake
Step 1: Preheat the Oven
Start by setting your oven to 375°F (190°C). This gives it enough time to fully heat while you prep the rest of your ingredients. A properly preheated oven is key to getting that perfectly browned, bubbly cheese top. Pro tip: If your oven runs a little cool (some do!), you might want to use an oven thermometer to be sure you’re baking at the right temperature.
Step 2: Sauté Onion and Garlic
In a large skillet over medium heat, add two tablespoons of olive oil. Once the oil is hot, toss in your chopped onion and minced garlic. Let them cook for about 3–4 minutes, stirring occasionally. You’re looking for the onions to turn soft and translucent and the garlic to become fragrant—not brown. This step lays the flavor foundation for the entire dish, so don’t rush it. If your onions are burning too quickly, turn the heat down slightly.
Want a shortcut? You can prep your onions and garlic ahead of time and store them in the fridge for up to two days. Check out our ingredient prep tips for more make-ahead ideas.
Step 3: Brown the Ground Beef
Add the ground beef to your skillet with the sautéed aromatics. Break it up with a wooden spoon or spatula and stir frequently so it browns evenly. Cook for 5–7 minutes or until the beef is fully cooked with no pink left. If your beef releases a lot of fat, you may want to drain the excess grease before moving to the next step—especially if you’re aiming for a leaner low-carb meal.
Using ground turkey or chicken instead? Totally fine. For more ideas, check out our Easy Homemade Beefy Melt Burritos for flavor inspiration with other proteins.
Step 4: Add Bell Peppers and Seasonings
Now it’s time to add in the sliced red and green bell peppers. These not only add color but a subtle sweetness and slight crunch. Sprinkle in your salt, black pepper, and Italian seasoning. Stir everything together and let it cook for another 5 minutes. This softens the peppers slightly while letting them soak up all that beefy, garlicky flavor.
Looking to mix it up? Feel free to toss in mushrooms, spinach, or even diced zucchini. Our Low Carb Mexican Soup is a great example of how to get creative with low-carb veggie combos.
Step 5: Transfer to Baking Dish
Now take your beef and pepper mixture and divide it between two individual-sized foil pans or pour everything into one 8×8 baking dish—whatever you have on hand works. This makes cleanup a breeze, especially if you’re meal prepping for the week or cooking for one.
Step 6: Add the Cheese Layers
Sprinkle an even layer of shredded cheddar cheese followed by mozzarella cheese over the beef mixture. This duo gives you the best of both cheesy worlds: cheddar for sharpness and mozzarella for that gooey melt factor. Don’t skimp—the cheese is what ties it all together and gives it that indulgent baked texture without the carbs.

Step 7: Bake to Cheesy Perfection
Place your dish (or foil pans) on a baking sheet—this makes it easier to handle and catches any cheesy spills—and bake in your preheated oven for 15–20 minutes. You’re looking for melted, bubbling cheese with golden edges. If you’re a fan of crispier cheese on top, you can broil it for an additional 2–3 minutes, but keep a close eye on it.
Step 8: Let It Rest and Serve
Once it’s done baking, remove it from the oven and let it sit for 5 minutes before serving. This helps everything set up a bit, making it easier to scoop and even more flavorful. Serve it hot with a side salad or low-carb veggie, or just eat it straight out of the pan—we won’t judge.

What to Serve with Low Carb Beef and Pepper Cheesy Bake
This dish can totally stand on its own, but if you want to round it out, there are some great pairings. For a low-carb plate, try a fresh side salad with a tangy vinaigrette, or some roasted cauliflower or zucchini noodles for extra veggies. If you’ve got a family who isn’t low-carb, you can easily serve it with rice, crusty bread, or even a quick buttered pasta on the side. You can also pair it with Low Carb Mexican Soup if you’re feeling a cozy two-dish vibe. The cheesy bake is flexible like that—it fits in with whatever mood your dinner table is having.
Key Tips for Making Low Carb Beef and Pepper Cheesy Bake
Want to make this dish even smoother? Here are some quick tips: Use pre-shredded cheese to save time, but grate your own if you want better melt and fewer additives. Don’t overcook the bell peppers—they should be just tender, not mushy. If your beef releases a lot of fat, drain it before adding the peppers so your dish doesn’t turn greasy. Craving more flavor? Add a pinch of red pepper flakes or swap Italian seasoning for taco seasoning for a Tex-Mex twist. And finally, use a cast iron skillet if you have one—you can go from stovetop to oven without dirtying another dish.
Storage and Reheating Tips Low Carb Beef and Pepper Cheesy Bake
Got leftovers? Lucky you. This dish stores well for up to 4 days in the fridge. Let it cool completely before popping it into an airtight container. Reheat individual portions in the microwave (about 1–2 minutes on high), or reheat the whole dish in a 350°F oven for 10–15 minutes, covered with foil. You can also freeze it—just wrap it tightly and store for up to 2 months. When you’re ready, thaw in the fridge overnight and bake until hot. It’s a great make-ahead meal when you need something quick but satisfying.
