Ingredients

• 2 large Zucchini (sliced lengthwise into 1/8‑inch strips)
• 1 pound Sweet Italian Sausage (casing removed; can substitute ground beef)
• 2 cups Low‑Sugar Marinara Sauce (look for ≤4 net carbs per half‑cup; brand used was a store‑brand from Ralph's)
• 1/3 cup Onion (diced; about 1 small onion)
• 2 cloves Garlic (minced)
• 1 tablespoon Olive Oil (for sautéing onion and garlic)
• 1 teaspoon Dried Oregano
• 1/2 teaspoon Crushed Red Pepper Flakes (optional for a mild kick)
• 2 tablespoons Fresh Basil (chopped; divided between sauce and garnish)
• 1/4 teaspoon Black Pepper (freshly ground)
• 1/2 teaspoon Salt (plus a pinch for ricotta mixture)
• 16 ounces Whole Milk Ricotta (full‑fat for best texture)
• 2 large Eggs (beaten; acts as binder)
• 2 cups Shredded Mozzarella Cheese (divided for layers and topping)
• 1/2 cup Asiago Cheese (grated; for finishing topping)
• 1 teaspoon Low‑Carb Sweetener (optional; balances acidity (erythritol or monk fruit))

Instructions

1. Slice and Sweat the Zucchini

   Trim the ends of the zucchini and slice lengthwise into 1/8‑inch strips using a mandoline or sharp knife. Place the strips in a single layer on a large plate, sprinkle lightly with salt, and let sit for 10 minutes to draw out moisture. Pat the strips dry with paper towels.

   Time: PT15M

2. Prepare the Low‑Carb Sauce

   Heat 1 tbsp olive oil in a large cast‑iron skillet over medium heat. Add the diced onion and sauté 4‑5 minutes until translucent. Add minced garlic and cook another 30 seconds. Crumble the sausage into the pan, breaking it up, and brown for 5‑6 minutes. Sprinkle in 1 tsp dried oregano, 1/2 tsp red‑pepper flakes, and 1/2 tsp fresh basil. Pour in the marinara sauce, stir, and bring to a gentle simmer. Add 1 tsp low‑carb sweetener, taste, and adjust with a pinch more oregano, salt, or pepper if needed. Simmer 5‑7 minutes until the sauce thickens slightly.

5. Assemble the Lasagna

   Spread a thin layer of sauce on the bottom of the 9x9 baking dish. Layer half of the zucchini strips, then spread half of the ricotta mixture, sprinkle 1/2 cup shredded mozzarella, and drizzle more sauce. Repeat with the remaining zucchini, ricotta, mozzarella, and sauce. Finish with the remaining mozzarella and the grated asiago on top. Scatter the remaining fresh basil leaves for color.

   Time: PT10M

6. Bake

   Cover the dish loosely with aluminum foil and bake for 20‑25 minutes, until the sauce is bubbling and the cheese is melted.

   Time: PT25M

7. Broil for a Golden Top

   Remove the foil and switch the oven to broil. Broil for 4‑5 minutes, watching closely, until the cheese turns a deep golden brown.
