How to Make Zesty Zucchini Beef Casserole Recipe

Step 1: Prep the Oven and Baking Dish

Start by preheating your oven to 375°F (190°C), giving your casserole the ideal environment for golden, bubbly cheese. Lightly grease a 9×13-inch baking dish with a little oil or cooking spray so nothing sticks and those browned cheesy edges come out intact.

Step 2: Brown the Beef

Heat that olive oil in a large skillet over medium-high and add your ground beef. Use a spoon to break it into small crumbles as it cooks, making sure each bit becomes beautifully browned—this is where you lay down the savory flavor base for the entire casserole!

Step 3: Sauté Onions and Garlic

Once your beef is just about browned, toss in the diced onion and minced garlic. Stir everything together and let it all soften and marry in the skillet for about 2 minutes. Your kitchen should be smelling fantastic by now.

Step 4: Add Zucchini and Red Bell Pepper

Scoot in those sliced zucchinis and diced red bell pepper. Sauté, stirring now and then, for 4 to 5 minutes until the zucchini is just tender and the peppers bright. This step adds gorgeous color and balances the rich, meaty base.

Step 5: Stir in Tomatoes, Spices, and Simmer

Fold in the diced tomatoes with green chilies, tomato sauce, Italian seasoning, chili powder, salt, and black pepper. Give it a good stir to meld everything, then let the pan simmer for around 5 minutes. The flavors blend and grow bolder as they bubble together!

Step 6: Assemble and Top with Cheese

Pour your zesty beef and veggie mixture into the prepared baking dish, spreading it evenly. Generously sprinkle cheddar, mozzarella, and Parmesan cheese all across the top. Each layer of cheese will melt differently, creating irresistible pockets of flavor.

Step 7: Bake Until Bubbly

Pop the baking dish into your preheated oven and bake, uncovered, for 20 to 25 minutes. You’re looking for that magical moment when the cheese is melted, browned, and bubbling at the corners—it’s casserole perfection!

Step 8: Garnish and Enjoy

To finish your Zesty Zucchini Beef Casserole Recipe, scatter fresh parsley over the hot, cheesy top. It adds a bright, herbal lift and shows off the fresh ingredients you layered inside. Let it cool for a minute, then dig in!
