Step‑by‑Step Instructions for Low-Carb Zucchini Lasagna
Step 1: Prepare Zucchini
Trim the ends of your zucchini and slice it lengthwise into ¼-inch planks for optimal layering. Toss these slices with extra-virgin olive oil, kosher salt, and ground black pepper. Grill or broil the zucchini slices on medium-high for about 5-8 minutes, until lightly browned and tender. Once done, pat them dry with a paper towel to remove excess moisture, which will help keep your zucchini lasagna from becoming watery.
Step 2: Brown the Meat
In a large skillet, heat the remaining olive oil over medium heat. Add the lean ground beef or ground bison to the skillet along with kosher salt and dried oregano. Cook for about 7-10 minutes, stirring occasionally, until the meat is browned and no longer pink. Stir in minced garlic and continue cooking for an additional 30 seconds, inhaling that delicious aroma as you prepare to mix in the marinara sauce. Combine well and set aside.
Step 3: Mix Filling
In a mixing bowl, combine low-fat cottage cheese (or ricotta if preferred) with half of the grated Parmesan cheese, a large egg, and a pinch of salt and pepper. Stir in the thawed and well-drained frozen chopped spinach until all ingredients are evenly mixed. This creamy filling will create a luscious layer in your zucchini lasagna, enhancing its richness and flavor.
Step 4: Assemble Lasagna
Preheat your oven to 350°F (175°C) while you assemble. In a greased 9×13-inch casserole dish, start by layering half of the prepared meat sauce at the bottom. Next, add half of the grilled zucchini slices, followed by the entire cheese mixture. Repeat the layers with the remaining zucchini and meat sauce, ensuring a hearty assembly. Finally, top the lasagna with shredded part-skim mozzarella cheese and the remaining grated Parmesan cheese for that delightful melty finish.
Step 5: Bake
Place your assembled zucchini lasagna in the preheated oven and bake for approximately 20 minutes, or until the cheese is bubbly and lightly golden. Keep an eye on the top to avoid burning, as the melted mozzarella should be invitingly gooey. Once baked, remove from the oven and let it cool for a few minutes before slicing.
Step 6: Garnish and Serve
Before serving, sprinkle freshly chopped basil over the top of your zucchini lasagna for a burst of color and flavor. This delightful touch of herbiness will elevate your dish, making it even more inviting. Serve warm and enjoy the hearty, satisfying layers that redefine comfort food in a low-carb style!
