How to Make Cheesy Beef & Zucchini Casserole
Step 1: Preheat Your Oven
First things first—let’s get that oven preheating to 375°F (190°C). A hot oven ensures that our casserole cooks evenly and gives us that lovely bubbly cheese we all crave!
Step 2: Sauté the Aromatics
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add your chopped onion and minced garlic. Sauté them for about 2-3 minutes until the onion becomes translucent. This step is crucial as it helps release those sweet flavors from the onions while infusing your dish with aromatic goodness.
Step 3: Brown the Beef
Next up, add 1 pound of ground beef to your skillet. Use a spatula to break it apart as it cooks. Stir until it’s nicely browned—this should take about 5-7 minutes. If there’s any excess fat, feel free to drain it off so we keep our casserole light yet delicious!
Step 4: Mix in the Veggies
Now it’s time to add those beautiful sliced zucchinis along with the drained diced tomatoes, Italian seasoning, salt, and pepper. Cook everything together for another 5 minutes so that the zucchini softens slightly but still retains its texture. You want that nice balance between tender and crisp!
Step 5: Assemble Your Casserole
Once your beef and veggie mixture is ready, transfer it into a greased 9×13-inch baking dish. Spread everything out evenly; this ensures every bite has that wonderful mixture of flavors.
Step 6: Top with Cheese
Now comes my favorite part—sprinkling shredded cheddar and mozzarella cheese all over the top! If you’re feeling adventurous, add breadcrumbs for an extra crunch on top. It not only adds texture but also makes the dish visually appealing.
Step 7: Bake Until Golden
Pop your casserole into the preheated oven and bake for about 25-30 minutes. Keep an eye on it until the cheese is bubbly and golden brown—this is where all that deliciousness happens!
Step 8: Serve and Enjoy!
Once done baking, let your Cheesy Beef & Zucchini Casserole cool slightly before serving—it’ll be hard to resist but worth waiting just a minute! Serve it up warm and watch as everyone digs in with big smiles on their faces. Enjoy every cheesy bite!
