How to Make Keto Lasagna
-
Preheat the oven to 350°F, while lightly greasing a square 8-inch baking dish. This initial step ensures your lasagna bakes evenly and won’t stick!
-
Defrost the spinach in the microwave according to the package directions, and then drain thoroughly. Squeeze out any excess water; the more moisture you remove, the better your layers will hold together.
-
Sauté the beef, onion, and ½ teaspoon of kosher salt in a large skillet over medium-high heat. Cook until the onion is soft and the meat is browned, about 5-7 minutes. The aroma will fill your kitchen—enjoy this moment!
-
Mix in the garlic and cook for 30 seconds until fragrant, then add the marinara sauce and turn off the heat. This melds all those delicious flavors together!
-
Soften the cream cheese in a medium microwave-safe bowl for 40 seconds. Stir until smooth, then whisk in the egg, black pepper, and the remaining ½ teaspoon of kosher salt. Add the drained spinach, mixing until well combined.
-
Spread the spinach mixture evenly on the bottom of the prepared baking dish. Layer the beef mixture on top, followed by a generous sprinkle of mozzarella cheese.
-
Bake the lasagna for about 30 minutes until the cheese is bubbly and lightly browned. Keep an eye on it to achieve that perfect golden hue!
-
Let the lasagna stand for ten minutes before cutting and serving. This helps the layers set, making it easier to serve those beautiful squares!
Optional: Garnish with fresh basil for a fresh flavor twist.

Expert Tips for Keto Lasagna
• Defrost Smartly: Ensure spinach is defrosted and thoroughly drained. Excess moisture can lead to a soupy lasagna rather than the desired layers.
• Brown It Right: When cooking the ground beef, make sure it’s well-browned. This enhances the flavor and texture, turning this Keto Lasagna into a mouthwatering dish.
• Creamy Consistency: For the spinach mixture, ensure that the cream cheese is softened well before mixing. This creates a smoother, creamier layer that melds beautifully.
• Bake and Check: Keep an eye on the lasagna as it bakes. If you’re looking for that golden cheese top, consider broiling for an extra minute for a delightful finish—but don’t walk away!
• Let It Rest: Always allow the lasagna to cool for about ten minutes before serving. This helps set the layers and makes for cleaner cuts when you serve.
Enjoy your Keto Lasagna journey, and remember, the secret is in the details!

Spinach Beef Lasagna Recipe FAQs
How do I select the best spinach for my Keto Lasagna?
Absolutely! When choosing spinach, look for bright green leaves without any dark spots or wilting. Frozen chopped spinach is a great and convenient option, but if you’re opting for fresh, make sure it feels crisp and smells fresh.
How should I store leftover Keto Lasagna?
To keep your delicious Keto Lasagna fresh, store any leftovers in an airtight container in the fridge for up to 3 days. This ensures your flavors stay intact, and it’s ready for a quick reheat when hunger strikes!
Can I freeze my Keto Lasagna?
Very! Freezing is a wonderful option for meal prep. To freeze, slice the lasagna into individual portions and wrap each one tightly in plastic wrap, then in foil. This prevents freezer burn and allows you to enjoy it later. You can store it in the freezer for up to 3 months.
What’s the best way to reheat frozen Keto Lasagna?
When you’re ready to enjoy your frozen Keto Lasagna, first thaw it overnight in the fridge. Then, preheat your oven to 350°F and reheat for about 20-25 minutes, or until warmed through and the cheese is melting again.
What should I do if my lasagna turns out too watery?
If you find your Keto Lasagna is a bit watery, it often means that not enough moisture was removed from the spinach or the beef wasn’t drained properly. For future attempts, squeeze out as much water as possible from the spinach after defrosting, and drain the beef mixture thoroughly after cooking to keep those layers intact.
Are there any dietary considerations for the Keto Lasagna?
Certainly! This recipe includes ingredients like cream cheese and beef, which some may want to avoid for dietary or allergy reasons. If you have lactose intolerance, you can substitute with a dairy-free cream cheese alternative. Similarly, for those with beef allergies, ground turkey or chicken can serve as a lean alternative in your Keto Lasagna.
