Instructions
Prepare the Fathead Dough Noodles
- In a large microwave-safe bowl, combine 1.5cups shredded mozzarella cheese and 2tbsp cream cheese. Microwave in 30-second intervals, stirring between each, until fully melted and smooth.
- Add 3/4cup almond flour and 1large egg to the melted cheese mixture, stirring vigorously until a dough forms.
- Place the dough between two sheets of parchment paper and roll it out to a thin, even rectangle about 1/8-inch thick.
- Remove the top parchment paper, transfer the dough (still on the bottom parchment paper) to a baking sheet, and bake at 375°F for 10 minutes, or until firm but not browned. Let cool, then cut into lasagna-sized sheets.
Prepare the Meat Sauce
- In a large skillet over medium heat, cook 1lb ground beef and 1lb Italian sausage, breaking it apart with a wooden spoon, until fully browned and cooked through. Drain excess grease if needed.
- Stir in 2cups low-carb marinara sauce, 1tsp garlic powder, 1tsp onion powder, 1tsp Italian seasoning, and 1/2tsp red pepper flakes (if using). Simmer for 5-7 minutes, allowing the flavors to meld. Adjust salt and pepper to taste. Remove from heat.
Prepare the Cheese Mixture
- In a mixing bowl, combine 1.5cups ricotta cheese, 1large egg, 1/4tsp ground nutmeg (if using), 1/2cup grated Parmesan cheese, and 1cup shredded mozzarella cheese. Stir until smooth and evenly mixed.
Assemble the Lasagna
- Spread a thin layer of meat sauce (about 1/2cup) evenly over the bottom of a greased 9x13-inch baking dish.
- Lay one layer of fathead dough noodles over the sauce. Top with 1/3 of the ricotta mixture, 1/3 of the remaining meat sauce, and 1/3 of the shredded mozzarella cheese.
- Repeat this layering process (noodles, ricotta, meat sauce, mozzarella) two more times, ending with a final layer of shredded mozzarella and a sprinkle of 1/4cup grated Parmesan cheese.
Bake the Lasagna
- Cover the baking dish with aluminum foil, ensuring the foil doesn’t touch the cheese, and bake at 375°F for 20 minutes.
- Remove the foil and bake for an additional 15 minutes, or until the cheese is golden and bubbly.
Rest and Serve
- Allow the lasagna to rest for 10 minutes before slicing to let the layers set.
- Garnish with 2tbsp chopped fresh parsley before serving.
Notes
- Fathead Dough Mastery: Rolling out the fathead dough evenly is key to achieving perfect layers. If the dough feels too sticky, sprinkle a small amount of almond flour on your parchment paper. Make sure to bake the dough lightly to prevent sogginess but don’t overbake, as it still needs to absorb the sauce during baking.
- Cheese Choices Matter: Whole milk ricotta and mozzarella create the richest, creamiest layers. If you prefer a sharper flavor, feel free to mix in a bit of shredded aged provolone or fontina cheese.
- Meat Sauce Secrets: A mix of ground beef and Italian sausage adds depth and boldness to the lasagna. For a smoky twist, use smoked paprika or swap Italian sausage with chorizo. Make sure to let the sauce simmer long enough for the flavors to meld beautifully.
- Low-Carb Marinara Recommendations: Rao’s Homemade Marinara is a keto favorite due to its rich flavor and minimal sugar content. If you’re feeling adventurous, try making your own marinara using crushed San Marzano tomatoes, garlic, and Italian herbs.
- Meal Prep Champion: This lasagna tastes even better the next day! Store leftovers in an airtight container in the refrigerator for up to 4 days, or freeze individual portions for up to 3 months.
- Pro Tip for Serving: Garnish each slice with a drizzle of extra virgin olive oil and a sprinkle of fresh Parmesan right before serving for an added layer of luxury.
- Fun Fact: Lasagna dates back to ancient Greece, where it was called “laganon,” a dish made of pasta and sauce. Today, our keto version brings a modern twist to this classic, combining culinary history with health-conscious innovation.
