A hearty, cheesy low-carb casserole made with seasoned ground beef, tender zucchini, tomatoes, and melted cheese. It’s easy to prepare, naturally satisfying, and great for a family dinner.
Ingredients
For the Beef & Zucchini
1 lb (450 g) ground beef, preferably 85–90% lean
3 medium zucchini, sliced into thin rounds or half-moons
½ medium onion, finely diced
3 cloves garlic, minced
1 cup diced tomatoes, drained
1 tablespoon olive oil
1 teaspoon Italian seasoning
1 teaspoon paprika
½ teaspoon onion powder
½ teaspoon salt
¼ teaspoon black pepper
¼ teaspoon red pepper flakes, optional
For the Creamy Cheese Layer
4 oz (115 g) cream cheese, softened
½ cup sour cream
½ cup shredded mozzarella
½ cup shredded cheddar cheese
1 tablespoon fresh parsley, chopped
For the Topping
1 cup shredded mozzarella cheese
¼ cup shredded cheddar cheese
1 tablespoon grated Parmesan cheese
1 tablespoon chopped fresh parsley
Instructions
1. Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
2. Prepare the Zucchini
Slice the zucchini into thin, even pieces.
Place the zucchini in a large bowl and sprinkle lightly with salt. Let it sit for about 10 minutes.
Pat the zucchini thoroughly dry with paper towels. This step helps prevent the casserole from becoming watery.
3. Brown the Ground Beef
Heat olive oil in a large skillet over medium-high heat.
Add the diced onion and cook for 2–3 minutes.
Add the ground beef and cook for 6–8 minutes, breaking it apart with a spoon until browned and fully cooked.
Drain excess grease if necessary.
4. Season the Beef
Add the garlic, Italian seasoning, paprika, onion powder, salt, black pepper, and optional red pepper flakes.
Cook for another 1 minute, until fragrant.
Stir in the drained diced tomatoes and cook for 2–3 minutes.
Remove from the heat.
5. Prepare the Creamy Cheese Mixture
In a bowl, combine:
Softened cream cheese
Sour cream
½ cup mozzarella
½ cup cheddar
Fresh parsley
Mix until smooth and creamy.
6. Assemble the Bake
Arrange approximately half of the zucchini slices in the bottom of the prepared baking dish.
Spread half of the seasoned beef mixture over the zucchini.
Spoon half of the creamy cheese mixture over the beef.
Repeat with the remaining zucchini, beef, and creamy cheese mixture.
7. Add the Cheese Topping
Sprinkle the remaining mozzarella and cheddar evenly over the top.
Finish with Parmesan cheese.
8. Bake
Cover the dish loosely with aluminum foil and bake for 25 minutes.
Remove the foil and continue baking for another 15–20 minutes, until the zucchini is tender and the cheese is melted and golden.
For a more browned top, place the casserole under the broiler for 1–2 minutes, watching carefully.
9. Rest and Serve
Remove from the oven and allow the casserole to rest for 10 minutes.
Sprinkle with fresh parsley before serving.
Tips for the Best Low-Carb Zucchini Bake
Don’t skip drying the zucchini. Zucchini releases a lot of water while cooking.
Slice zucchini evenly so it cooks at the same rate.
For extra flavor, brown the beef well before adding the seasonings.
If using very lean beef, add an extra teaspoon of olive oil while cooking.
Let the casserole rest before cutting so the layers can set.

Recipe Q&A
Q: Is this recipe keto-friendly?
Yes, it can fit a keto or low-carb diet because zucchini replaces higher-carb ingredients such as potatoes or pasta. Exact carbohydrates depend on the brands and quantities used.
Q: Can I use ground turkey instead of beef?
Yes. Ground turkey or chicken works well, although the casserole will have a lighter flavor.
Q: Can I use frozen zucchini?
Fresh zucchini is strongly recommended. Frozen zucchini releases more water and can make the casserole soggy.
Q: Can I prepare this ahead of time?
Yes. Assemble the casserole, cover it, and refrigerate for up to 24 hours. Bake when ready, adding a few extra minutes if necessary.
Q: Can I freeze it?
Yes, but zucchini can become softer after freezing and thawing. For best texture, freeze the cooked beef mixture separately and assemble with fresh zucchini.
Q: How do I keep the casserole from becoming watery?
Salt and drain the zucchini, pat it very dry, drain the tomatoes, and avoid overcooking the zucchini before assembling.
Q: Can I make it without cream cheese?
Yes. You can replace the cream cheese with ricotta, cottage cheese, or additional shredded cheese.
Q: What cheese works best?
Mozzarella gives excellent melting, while cheddar adds stronger flavor. Monterey Jack, Colby Jack, or provolone can also be used.
Q: What should I serve with it?
For a low-carb meal, serve it with a green salad, roasted broccoli, cauliflower rice, asparagus, or steamed green beans.
Q: How long do leftovers last?
Store leftovers covered in the refrigerator for up to 3–4 days. Reheat individual portions in the microwave or oven until hot.
