Step-by-Step Instructions

Step 1: Sauté the Beef and Veggies
Start by heating a tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and garlic, sautéing for about 2-3 minutes until they become fragrant and softened. Then, add the ground beef to the skillet, breaking it apart with a spoon. Cook the beef for about 5-7 minutes, until it’s browned and fully cooked through. Drain any excess fat if needed.
Step 2: Add Zucchini and Tomatoes
Once the beef is ready, toss in the sliced zucchini and the drained diced tomatoes. Stir everything together and cook for another 3-4 minutes until the zucchini begins to soften. You’ll want the zucchini to retain some texture, so avoid overcooking.
Step 3: Mix in the Cream and Seasoning
Lower the heat to medium-low. Pour in the heavy cream and sprinkle in the Italian seasoning. Stir until the mixture is well combined. Season with salt and pepper to taste. The creamy sauce will start to thicken and coat the beef and vegetables beautifully.
Step 4: Add Cheese
Sprinkle in the shredded cheddar cheese and stir it through the mixture until it melts and creates a creamy texture. For a crispy topping, sprinkle the Parmesan cheese over the top at this stage. Let the dish simmer for an additional 2-3 minutes, ensuring the cheese is evenly distributed.
Step 5: Serve
Once the casserole is bubbling and the cheese is melted, it’s ready to serve! Spoon the casserole onto plates or into bowls, and enjoy the warm, cheesy goodness.

Common Mistakes to Avoid
Even though making Hamburger Zucchini Casserole is straightforward, there are a few common pitfalls to avoid:
- Overcooking the zucchini: Zucchini releases a lot of water. If you overcook it, the casserole will become watery. Aim for just a light sauté to retain its texture.
- Too much liquid: Adding too much cream or broth can result in a soggy casserole. Stick to the measurements to avoid diluting the creamy sauce.
- Under-seasoning: Don’t forget to taste and adjust the seasoning throughout the process. The flavors need a good balance of salt, pepper, and Italian seasoning.
Storing Tips for the Recipe
If you have leftovers (which is likely!), here’s how to store them:
- Refrigerate: Store any leftover casserole in an airtight container in the fridge for up to 3 days.
- Freeze: This casserole also freezes well! Simply let it cool to room temperature before transferring to a freezer-safe container. It will keep in the freezer for up to 3 months. When you’re ready to eat, thaw in the fridge overnight and reheat in the oven or microwave.
