Cooking Time & Prep Time

Prep Time: 15–20 minutes
Cooking Time: 3–4 hours on LOW or 2–2.5 hours on HIGH

Ingredients

• 1 pound ground beef (or ground turkey)
• 1 small onion, diced
• 2 cups uncooked pasta (penne or rotini work best)
• 1 jar (24 oz) pizza or pasta sauce
• 1 can (14 oz) diced tomatoes, drained
• 2 cups shredded mozzarella cheese
• 1 cup shredded cheddar or pizza cheese blend
• 1 cup sliced pepperoni
• 1 green bell pepper, diced
• 1 teaspoon garlic powder
• 1 teaspoon Italian seasoning
• Salt and pepper to taste
• Optional toppings: mushrooms, olives, cooked sausage, spinach, or chili flakes

Step-by-Step Instructions

Step 1: Cook the Meat

Place a skillet on medium heat. Add ground beef and diced onion. Cook until the meat is brown and no pink remains. Drain extra grease. Add garlic powder, Italian seasoning, salt, and pepper.

Step 2: Prepare the Crockpot

Spray the inside of your crockpot with non-stick spray. This helps prevent sticking and makes cleanup easier.

Step 3: Layer the Ingredients

Pour the uncooked pasta into the bottom of the crockpot. Add the cooked meat and onions on top. Pour the pasta sauce and diced tomatoes over everything. Add diced green pepper and half of the pepperoni slices. Stir lightly to combine the layers without over-mixing.

Step 4: Add Cheese

Sprinkle 1 cup of mozzarella and half of the cheddar cheese on top of the mixture. Do not stir. This helps create a gooey top layer as it cooks.

Step 5: Cook

Cover the crockpot. Cook on LOW for 3–4 hours or on HIGH for 2–2.5 hours. Avoid opening the lid too often. This slows down the cooking process.

Step 6: Final Topping

When the pasta is tender, add the remaining cheese and pepperoni on top. Cover again and cook for 5–10 minutes until the cheese melts fully.

Step 7: Serve

Scoop into bowls or plates. Let it cool slightly before eating because it stays very hot inside the crockpot.

Tips & Variations

• Vegetarian: Replace the meat with mushrooms, spinach, or plant-based meat. Use vegetarian pepperoni slices for the topping.
• Vegan: Use vegan cheese and plant-based meat. Make sure the pasta sauce is dairy-free.
• Gluten-Free: Use gluten-free pasta. Check your sauce and pepperoni to make sure they are gluten-free.
• Extra Creamy: Stir in half a cup of cream cheese or ricotta during the last 30 minutes of cooking.
• More Heat: Add chili flakes, jalapeños, or spicy sausage.
• More Veggies: Add zucchini, carrots, or mushrooms for extra flavor and nutrients.

Tip: If the mixture looks too thick while cooking, add ¼ cup water or broth and stir lightly.

Health Benefits

This dish offers a balance of protein, carbs, and fats. The ground beef or turkey provides protein for muscle strength. Vegetables like onions, peppers, and tomatoes add vitamins and antioxidants. Pasta gives you energy, especially helpful on busy days. If you add more veggies or use lean turkey, the dish becomes lighter but still satisfying. Cooking in a crockpot also helps keep nutrients in the food because it cooks slowly at a lower temperature.

Serving Suggestions

Serve this casserole with a simple green salad or garlic bread for a full meal. It also tastes great with steamed vegetables on the side.
Leftovers store well in the fridge for up to 3 days. Place them in an airtight container. To reheat, warm in the microwave or on the stove with a splash of water to keep it moist.
You can also freeze leftovers for up to 2 months. Reheat from frozen in the microwave or let it thaw overnight in the fridge.
