How to Make Keto Zucchini Beef Casserole

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). Lightly grease a 7×11-inch casserole dish to prevent sticking.

Step 2: Cook the Beef

Heat a large skillet over medium-high heat and lightly grease it. Add ground beef and cook for 5–7 minutes, breaking it apart as it browns. Season with garlic powder, onion powder, Italian seasoning, salt, and black pepper.

Step 3: Add Zucchini

Stir in cubed zucchini and cook for about 1 minute, just until slightly softened but still firm.

Step 4: Make It Creamy

Add softened cream cheese to the skillet. Stir and cook for 2–3 minutes until fully melted and combined into a creamy mixture.

Step 5: Add Cheese to Mixture

Remove from heat and mix in ¼ cup cheddar and ¼ cup mozzarella. Stir until evenly incorporated.

Step 6: Assemble the Casserole

Transfer the mixture into the prepared casserole dish. Spread evenly, then top with the remaining cheddar and mozzarella cheeses.

Step 7: Bake

Bake for 10 minutes, or until the cheese is fully melted, bubbly, and slightly golden.

Step 8: Garnish and Serve

Remove from the oven and sprinkle with chopped parsley. Let it cool slightly before serving.

Tips for Success

• Don’t overcook zucchini in the skillet—it should stay slightly firm
• Soften cream cheese beforehand for easier mixing
