Instructions

Phase 1: Make the Meatballs (Intensity: Medium)

1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.

2. In a large bowl, combine ground beef, ground pork, almond flour, Parmesan, 1 egg, garlic, oregano, 1 tsp salt, and ½ tsp pepper. Mix gently with your hands until just combined (do not overwork, or meatballs will be tough).

3. Roll into 1.5-inch meatballs (about 20–24 meatballs).

4. Heat olive oil in a large skillet over medium-high heat. Sear meatballs in batches for 2–3 minutes per side, until browned. They will not be fully cooked inside. Transfer to a plate.

Phase 2: Prepare the Tomato Base (Intensity: Low)

1. In the same skillet, pour off excess fat but leave about 1 tbsp. Add marinara sauce and broth/water, scraping up browned bits from the bottom.

2. Simmer for 2 minutes. If using red pepper flakes, stir in now.

3. Pour half the sauce into the prepared baking dish. Arrange seared meatballs on top in a single layer. Cover with remaining sauce.

Phase 3: Veggie Egg Topping (Intensity: Medium)

1. In the same skillet (wipe clean), heat 1 tbsp olive oil over medium heat. Add onion and bell pepper. Sauté 3 minutes. Add zucchini and cook 3 more minutes. Add spinach and cook until wilted, about 1 minute. Season with salt and pepper. Remove from heat.

2. In a bowl, whisk together 6 large eggs, heavy cream, half the mozzarella, and fresh herbs. Season lightly.

3. Spread the sautéed vegetables evenly over the meatballs in the baking dish.

4. Pour the egg-cheese mixture over the vegetables, gently shaking the dish to let it seep down.

5. Sprinkle the remaining mozzarella on top.

Phase 4: Bake (Intensity: None)

1. Bake uncovered at 375°F (190°C) for 25–30 minutes, until the egg topping is set, lightly golden, and a knife inserted in the center comes out clean (or with slightly moist crumbs—not wet raw egg).

2. Let rest for 5 minutes before serving. The casserole will settle and become easier to slice.

Serving Suggestions

• Garnish with extra fresh parsley or basil.

• Serve with a side salad or crusty low-carb bread.

• Drizzle with pesto or hot sauce for extra flavor.

Storage & Reheating

• Refrigerator: Store in an airtight container for up to 4 days.

• Freezer: Freeze slices (without the egg topping? The eggs will change texture. Best to freeze meatball + veggie base, then add fresh egg mixture when rebaking.) For best results, freeze the assembled casserole before adding the egg topping, then add eggs and bake when ready.

• Reheat: Microwave individual portions for 1–2 minutes, or reheat in a 325°F oven for 10–15 minutes covered with foil.
