Key Ingredients

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Bell Peppers. I prefer using red, yellow, or orange varieties for maximum sweetness. They act as the sturdy, edible vessels that hold our delicious meat filling together perfectly.

Ground Beef. Selecting an 85/15 blend ensures the filling stays incredibly juicy throughout the baking process. It delivers the rich, savory foundation that pairs naturally with herbs.

Keto Marinara Sauce. Be sure to choose a high-quality brand with absolutely no added sugar. This component provides the essential acidic brightness and classic Italian aroma.

Mozzarella Cheese. Shredded whole-milk mozzarella creates that iconic, stretchy cheese pull on top. It melts beautifully into a golden crust during the final minutes.

Italian Seasoning. This simple blend of dried herbs adds instant depth and traditional pizzeria flavor. It elevates the ground beef without requiring a long list of individual spices.

How to make this Stuffed Bell Peppers Italian Style

Step 1- Brown the ground beef in a large skillet over medium heat until completely cooked.

Step 2- Stir the sugar-free marinara sauce and Italian seasoning directly into the browned meat.

Step 3- Slice the tops off your bell peppers and carefully remove all the seeds inside.

Step 4- Stuff the meat mixture tightly into the cavities of the prepared peppers.

Step 5- Place the peppers upright in a baking dish and cover them tightly with foil.

Step 6- Bake at 375°F for 30 minutes until the peppers become beautifully tender.

Step 7- Remove the foil, top generously with mozzarella cheese, and broil until golden brown.

Common Mistakes to Avoid

Using watery sauce: Cheap, thin sauces will make your peppers soggy, so always choose a thick marinara.
Skipping the foil cover: Baking without a cover dries out the meat before the peppers can soften properly.
Leaving seeds inside: Forgetting to clean the interiors leaves a bitter taste, so scrape them thoroughly.

Required Equipment

Large skillet: Browns the beef evenly while allowing flavors to combine beautifully.
9×9 baking dish: Holds the stuffed peppers upright so they do not fall over.
Sharp chef’s knife: Makes slicing the pepper tops clean, safe, and effortless.

Caleb’s Recipe Tips

If you want even softer peppers, try pre-baking the empty shells for 10 minutes before stuffing them. Trust me, I learned this the hard way after serving crunchy peppers to guests! Additionally, always let the cooked dish rest for five minutes before serving so the juices can settle. Finally, feel free to mix some parmesan into the beef for an extra savory kick.

Storage Instructions

You can store any leftover stuffed peppers in an airtight container inside the refrigerator for up to four days. If you wish to freeze them, place the cooled peppers in a freezer-safe bag for up to three months. When you are ready to eat, simply thaw them overnight in the fridge. Afterwards, bake at 350°F until the cheese is completely melted and bubbling.
