- Garlic: A little bit of garlic goes a long way to boost the overall flavor profile.
- Diced tomatoes: Brings a hint of acidity, moisture, and bright color to the dish.

- Mozzarella cheese: Melty, stretchy, and perfect for that classic casserole finish.
- Italian seasoning: A simple blend that unifies all the flavors with herbal notes.

How to Make Cheesy Beef & Zucchini Casserole
Step 1: Preheat Your Oven
Set your oven to 375°F (190°C) so everything bakes evenly and the cheese gets that irresistible golden finish. Preheating is always worth the few extra minutes!
Step 2: Sauté Onion and Garlic
In a large skillet, heat olive oil over medium heat. Toss in your chopped onion and minced garlic, cooking just until the onion softens and your kitchen fills with their fragrant aroma—usually about 2-3 minutes.
Step 3: Brown the Beef
Add the ground beef to the skillet with your onions and garlic. Use a spatula to break up the meat as it cooks, until it’s nicely browned and no pink remains. If there’s extra fat in the pan, give it a quick drain so your Cheesy Beef & Zucchini Casserole doesn’t turn out greasy.
Step 4: Add Zucchini, Tomatoes, and Seasoning
Now stir in your sliced zucchinis, drained diced tomatoes, Italian seasoning, plus a good sprinkle of salt and pepper. Let everything cook together for about five minutes—just enough for the zucchini to soften but not get mushy.
Step 5: Assemble in the Baking Dish
Grease a 9×13-inch baking dish, then pour in your beef and zucchini mix. Use a spatula to create an even layer so every bite gets all the flavors.
Step 6: Add Cheese (and Breadcrumbs!)
Evenly sprinkle the shredded cheddar and mozzarella cheeses all over your casserole. If you’re craving a bit of texture, go ahead and add a thin layer of breadcrumbs on top for a deliciously crisp finish.
Step 7: Bake to Golden, Bubbling Perfection
Slide your casserole into the oven and bake for 25–30 minutes, until the cheese is melted, bubbly, and beautifully golden around the edges. Trust me, it’s worth waiting for that top to get perfectly browned!
Step 8: Let It Set, Then Serve
When the Cheesy Beef & Zucchini Casserole comes out of the oven, let it cool slightly so it slices cleanly and doesn’t burn eager taste buds. Now all that’s left is to dig in and enjoy!
How to Serve Cheesy Beef & Zucchini Casserole
Garnishes
Add a sprinkle of fresh chopped parsley, basil, or a drizzle of olive oil over your Cheesy Beef & Zucchini Casserole just before serving. It not only brightens up the dish with color but adds a pop of fresh flavor too. A crack of black pepper is always welcome.
Side Dishes
This casserole is quite the star, but it loves some company! Try serving it alongside a simple green salad tossed in lemon vinaigrette, roasted vegetables, or a slice of warm garlic bread. These sides give your plate a beautiful balance and a touch of crunch.
Creative Ways to Present
For a fun twist, spoon Cheesy Beef & Zucchini Casserole into individual ramekins for personalized servings at a dinner party, or serve it family-style straight from the baking dish at your next potluck. You could even tuck it inside a wrap with some fresh greens for lunch the next day!
Make Ahead and Storage
Storing Leftovers
If you find yourself with extra Cheesy Beef & Zucchini Casserole, let it cool completely, then cover and refrigerate. It keeps well for up to four days, and the flavors only get better as they rest.
Freezing
Yes, you can freeze this casserole! Make sure it’s cooled down, then wrap portions tightly in plastic wrap and foil, or transfer to airtight containers. Freeze for up to three months for an easy future meal.
Reheating
To reheat, pop chilled or thawed casserole portions into a 350°F (175°C) oven until hot and bubbly—about 20 minutes for a big dish, or just a few minutes for single servings. If using a microwave, cover the serving with a damp paper towel to keep the cheese melty.
FAQs
Can I use ground turkey instead of beef?
Absolutely! Ground turkey works beautifully in this recipe. The flavors will be a bit lighter but still delicious with all the cheeses and zucchini.
What if I don’t have mozzarella cheese?
No problem—any good melting cheese will work. Try Monterey Jack, provolone, or even a mix of whatever you have on hand. Just don’t skip the cheese! It’s essential for that ooey-gooey top.
Do I need to peel the zucchini first?
No peeling required! The skin adds texture, color, and extra nutrients. Just rinse and slice; the zucchini will soften nicely in the oven.
Can this casserole be made vegetarian?
You bet! Swap the ground beef for cooked lentils, a plant-based crumble, or extra veggies like mushrooms and bell peppers. The Cheesy Beef & Zucchini Casserole will still taste wonderful as a veggie delight.
Should I cook the zucchini before adding to the casserole?
No need. Sautéing along with the beef is enough to soften it up without turning it mushy, so it bakes perfectly in the oven.
