• 1 medium Sweet Onion (diced)
• 4-5 Garlic Cloves (finely chopped)

How to Make Low Carb Zucchini Lasagna Casserole

Step 1: Preheat Your Oven

Preheat your oven to 375°F (190°C). This ensures that your casserole bakes evenly and reaches that perfect bubbly texture.

Step 2: Sauté Onions and Garlic

Heat olive oil in a large non-stick pan over medium heat. Add diced onions and sauté until softened—this should take about 4-5 minutes. Stir in garlic and cook for an additional minute. Sautéing until translucent brings out their natural sweetness, enhancing the overall flavor of your sauce.

Step 3: Brown the Ground Beef

Next, add in your ground beef. Cook until it’s no longer pink—about 5 minutes—using a wooden spoon to break it apart as it cooks. Properly browning the beef adds richness to your casserole.

Step 4: Create the Sauce

Stir in the tomato sauce along with Italian seasoning, salt and pepper, and smoked paprika. Let this simmer for about 8-10 minutes until the sauce reduces by half. This step is crucial as it intensifies all those delicious flavors!

Step 5: Prepare the Zucchini

While your sauce simmers, prepare your zucchini. Trim off the ends and slice them lengthwise into 1/4 inch thick strips. These layers will serve as your noodles, holding up beautifully under all that yummy filling.

Step 6: Layer It Up

In a 9-inch oval baking dish (or similar), start layering! Add one layer of zucchini slices at the bottom, followed by half of your meat sauce and then a layer of shredded mozzarella cheese. Repeat these layers, finishing off with mozzarella on top.

Step 7: Bake Until Bubbly

Sprinkle grated Parmesan cheese over the final layer of cheese before placing your dish in the oven. Bake for about 30-40 minutes or until hot and bubbly. The smell wafting through your home will be absolutely irresistible!

Pro Tips for Making Low Carb Zucchini Lasagna Casserole

Making a delicious Low Carb Zucchini Lasagna Casserole is easy with a few helpful tips!

• Use a mandoline slicer: This tool allows you to slice zucchini evenly, ensuring consistent cooking and texture throughout your casserole.
• Salt the zucchini: Before layering, sprinkle the sliced zucchini with salt and let it sit for about 15 minutes. This helps draw out excess moisture, preventing a watery casserole.
• Mix up the cheeses: Experiment with different cheeses like ricotta or cottage cheese mixed with herbs for added creaminess and flavor in your layers.
• Let it rest before serving: Allowing the casserole to sit for about 10 minutes after baking helps it set and makes it easier to slice without falling apart.
• Double the recipe: Since this dish freezes well, consider making a double batch! You can easily store leftovers for quick meals later on.
