How to Make Ground Beef and Veggie Casserole

Step 1: Prepare the Veggies

Start by washing and chopping your bell peppers, zucchini, and onion into bite-sized pieces. Mince the garlic finely to release its flavor quickly in the pan.

Step 2: Cook the Ground Beef

Heat olive oil in a large skillet over medium-high heat. Add the ground beef, breaking it up with a spoon, and cook until browned and cooked through. Drain excess fat if needed.

Step 3: Sauté the Vegetables

In the same skillet, add the chopped onions, bell peppers, and zucchini. Sauté until softened and fragrant, usually about 5-7 minutes. Toss in the minced garlic towards the end to avoid burning.

Step 4: Combine Meat and Veggies

Return the cooked ground beef to the skillet with the vegetables. Stir in tomato sauce and Italian seasoning, mixing everything thoroughly and letting the flavors meld for a couple of minutes on low heat.

Step 5: Assemble the Casserole

Preheat your oven to 375°F (190°C). Transfer the beef and veggie mixture into a baking dish. Sprinkle a generous layer of cheese over the top, followed by breadcrumbs for a crunchy finish.

Step 6: Bake and Serve

Bake uncovered for 20-25 minutes, or until the cheese is melted and golden brown on top. Let it rest briefly before serving to allow the casserole to set.

Pro Tips for Making Ground Beef and Veggie Casserole

• Choose Quality Meat: Use fresh, lean ground beef to keep the casserole flavorful and healthy.

• Season in Layers: Add salt, pepper, and herbs throughout cooking to build a richer flavor profile.
• Use Fresh Herbs: Fresh basil or parsley sprinkled on top after baking brightens the dish wonderfully.
• Watch the Cheese: Mix mozzarella for meltiness and cheddar for sharpness to balance gooey and bold flavors.
• Let it Rest: Allow the casserole to sit a few minutes after baking to make cutting and serving easier.
