🛒 Ingredients
For the Beef & Vegetables
- 🥩 2 lbs (900 g) lean ground beef
- 🫑 1 large green bell pepper, diced
- 🫑 1 large red bell pepper, diced
- 🧅 1 medium yellow onion, finely chopped
- 🫒 2 tablespoons olive oil
- 🧄 2 teaspoons garlic powder
- 🌿 1 teaspoon dried oregano
- 🌿 1 teaspoon dried basil
- 🧂 1 teaspoon salt, or to taste
- 🖤 ½ teaspoon black pepper
For the Tomato Sauce
- 🍅 1½ cups crushed tomatoes or marinara sauce
For the Cheese Topping
- 🧀 3 cups shredded mozzarella cheese
- 🧀 1 cup shredded cheddar or provolone cheese
- 🌿 Fresh parsley, chopped, for garnish
🔥 Instructions
Prepare the Oven
Preheat the oven to 400°F (200°C).
Lightly grease a 9 × 13-inch baking dish or rimmed sheet pan with olive oil.
Sauté the Vegetables
Heat the olive oil in a large skillet over medium-high heat.
Add the chopped onion and diced red and green bell peppers.
Cook for approximately 5–7 minutes, stirring occasionally, until the vegetables begin to soften.
Brown the Ground Beef
Add the ground beef to the skillet with the vegetables.
Break the beef apart with a wooden spoon or spatula and cook for approximately 7–9 minutes, or until it is completely browned.
Drain excess fat if necessary.
Season the Mixture
Add the garlic powder, dried oregano, dried basil, salt, and black pepper.
Stir well so the seasonings are evenly distributed throughout the beef and vegetables.
Add the Tomato Sauce
Pour in the crushed tomatoes or marinara sauce.
Stir everything together and simmer for approximately 3–4 minutes.
This allows the flavors to combine and gives the mixture a rich, savory consistency.
Transfer to the Baking Dish
Spread the beef and vegetable mixture evenly into the prepared baking dish or sheet pan.
Use a spatula to create an even layer so the cheese melts consistently across the top.
Add the Cheese
Sprinkle the shredded mozzarella evenly over the beef mixture.
Add the cheddar or provolone on top.
For an especially golden and bubbly finish, make sure the cheese reaches close to the edges of the dish.
Bake
Place the dish in the preheated oven.
Bake uncovered for approximately 15–20 minutes, or until the cheese is completely melted, bubbling, and lightly golden.
For a more deeply browned cheese topping, switch to the broiler for the final 1–2 minutes.
Watch carefully because the cheese can brown quickly.
Rest and Garnish
Remove the bake from the oven and let it rest for 5 minutes.
Sprinkle with freshly chopped parsley.
Slice and serve warm.
👩🍳 Best Tips
Use lean ground beef: This keeps the dish hearty without leaving too much excess grease.
Don’t overcook the vegetables: They should be tender but still have a little texture after baking.
Drain excess fat: If your ground beef releases a lot of fat, drain it before adding the tomato sauce.
Use freshly shredded cheese: Shredding cheese yourself can give you a smoother, more even melt.
Watch the broiler: If you want a golden cheese crust, stay close to the oven during broiling.
Let it rest: A short resting period helps the layers settle and makes serving easier.
🧀 Best Cheese Options
Mozzarella gives the dish its classic stretchy, melty texture.
Cheddar adds a stronger, richer flavor.
Provolone provides a mild, slightly smoky cheese flavor.
You can also combine mozzarella with Monterey Jack, Colby Jack, or a mild Italian cheese blend.
🌶️ Recipe Variations
Spicy Beef & Pepper Bake
Add crushed red pepper flakes or diced jalapeños to the beef mixture for extra heat.
Italian-Style Bake
Use marinara sauce, Italian seasoning, mozzarella, and provolone for a more pronounced Italian-inspired flavor.
Mushroom & Beef Bake
Add sliced mushrooms with the bell peppers and onions for extra savory flavor.
Extra Vegetable Version
Add zucchini, mushrooms, spinach, or diced tomatoes to increase the vegetable content.
Pizza-Inspired Version
Add sliced olives, mushrooms, bell peppers, and Italian seasoning before covering everything with mozzarella.
🍽️ What to Serve With It
This cheesy beef bake pairs beautifully with:
- 🥗 A crisp green salad
- 🥦 Roasted broccoli
- 🥒 Cucumber and tomato salad
- 🥬 Steamed vegetables
- 🥑 Avocado salad
- 🍅 A simple tomato salad
For a lighter meal, serve it with a large fresh salad or steamed vegetables.
⏰ Make-Ahead Instructions
You can prepare the beef and vegetable mixture up to 24 hours in advance.
Allow it to cool, transfer it to a covered baking dish, and refrigerate.
When ready to bake, add the cheese and bake at 400°F (200°C) until heated through and bubbling.
If the casserole is very cold from the refrigerator, it may require several additional minutes in the oven.
🧊 Storage
Allow leftovers to cool before placing them in an airtight container.
Refrigerate for up to 3–4 days.
♨️ Reheating
Reheat individual portions in the microwave until hot throughout.
For a better cheese texture, reheat portions in a 350°F (175°C) oven for approximately 10–15 minutes.
❄️ Freezing
This bake can be frozen in an airtight, freezer-safe container.
For best texture, freeze individual portions after they have completely cooled.
Thaw overnight in the refrigerator before reheating.
⚠️ Common Mistakes to Avoid
Adding too much sauce: Excess liquid can make the casserole watery.
Skipping the draining step: Very fatty beef can make the finished dish greasy.
Using too much cheese: A generous layer is delicious, but excessive cheese can overwhelm the other ingredients.
Overcooking the peppers: They can become mushy if cooked too long before baking.
Cutting immediately: Allowing the dish to rest for a few minutes makes it easier to serve.

❓ Frequently Asked Questions
Can I use ground turkey instead of ground beef?
Yes. Ground turkey works well as a leaner alternative. Because it can be less rich than beef, you may want to add a little extra seasoning.
Can I make this without a sheet pan?
Absolutely. A 9 × 13-inch baking dish works perfectly and may actually be easier for serving.
Can I make it ahead of time?
Yes. Prepare the beef and vegetable mixture, refrigerate it, then add the cheese and bake when you’re ready.
Can I make this low carb?
Yes. Use a low-carb tomato sauce or crushed tomatoes without added sugar and serve the bake without bread, pasta, or other high-carbohydrate sides.
How do I make the cheese extra golden?
Bake until melted, then place the dish under the broiler for 1–2 minutes. Keep a close eye on it because the cheese can brown very quickly.
