Ingredients for Keto Mexican Taco Lasagna

The ingredients for this Keto-friendly taco lasagna are simple, nutritious, and flavorful. Here’s what you’ll need to create this delicious dish.

For the Taco Meat Filling:

  • 1 lb ground beef (85% lean or higher for a leaner option)
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 packet taco seasoning (or homemade – recipe below)
  • 1/2 cup tomato sauce (look for sugar-free tomato sauce)
  • 1/4 cup water (or as needed)
  • 1 tablespoon olive oil (for cooking the meat)

For the Lasagna Layers:

  • 3 medium zucchinis, sliced thinly lengthwise (about 1/8-inch thick) – Zucchini replaces the pasta, giving the lasagna a fresh and low-carb base.
  • 2 cups shredded cheddar cheese (or a Mexican cheese blend for more flavor)
  • 1 cup shredded mozzarella cheese
  • 1/2 cup sour cream – Adds creaminess to the lasagna.
  • 1/4 cup green onions, chopped
  • 1/4 cup cilantro, chopped (optional but adds great flavor)

Optional Toppings:

  • Sliced jalapeños – For those who like a spicy kick.
  • Diced tomatoes – For extra freshness and color.
  • Avocado slices – A creamy, Keto-friendly addition.

Homemade Taco Seasoning (optional):

  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon crushed red pepper flakes (optional for heat)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions for Making Keto Mexican Taco Lasagna

Step 1: Prepare the Zucchini

The first step is to prepare the zucchini, which will act as the “noodle” layer in the lasagna. Slice the zucchinis lengthwise into thin strips, about 1/8-inch thick. You can use a mandoline slicer to achieve uniform slices. If your zucchinis are particularly watery, lay the slices out on paper towels, sprinkle lightly with salt, and allow them to sit for 10-15 minutes. This will help draw out excess moisture and prevent the lasagna from becoming too watery when baked.

Step 2: Cook the Ground Beef

In a large skillet, heat 1 tablespoon olive oil over medium-high heat. Add the chopped onion and cook for 2-3 minutes until softened. Add the garlic and cook for another minute, until fragrant.

Add the ground beef and break it up with a spoon as it cooks. Brown the beef for 6-8 minutes, until fully cooked through. Drain any excess fat if necessary. Once the beef is browned, add the taco seasoning (either the packet or your homemade seasoning blend) and tomato sauce. Add 1/4 cup of water to the pan, stirring until everything is well combined. Allow the mixture to simmer for 5-7 minutes until it thickens slightly. Remove the pan from heat.

Step 3: Assemble the Lasagna

Now that all the components are prepared, it’s time to assemble the lasagna!

Start by greasing a 9×13-inch baking dish with a bit of olive oil or cooking spray. Layer the bottom of the dish with zucchini slices, ensuring they cover the entire bottom without overlapping too much. Next, spread half of the taco meat mixture over the zucchini layer. Sprinkle 1/2 cup of shredded cheddar cheese and 1/2 cup shredded mozzarella cheese on top of the meat.

Next, add another layer of zucchini, followed by the remaining taco meat and cheese. Repeat the layers until all ingredients are used, finishing with a layer of cheese on top.

Step 4: Add Creamy Sour Cream

After assembling the lasagna, spread 1/2 cup sour cream over the top layer of cheese. This will create a creamy, delicious texture and help bind the lasagna together.

Step 5: Bake the Lasagna

Cover the baking dish with aluminum foil and bake the lasagna in a preheated oven at 375°F (190°C) for 25-30 minutes. After the initial bake, remove the foil and bake for an additional 10-15 minutes, or until the cheese on top is golden brown and bubbly.

Step 6: Garnish and Serve

Once baked, remove the lasagna from the oven and let it cool for a few minutes. This allows the layers to set and makes it easier to slice. Garnish with chopped green onions, cilantro, and any other optional toppings like sliced jalapeños, diced tomatoes, or avocado slices.

Serve warm and enjoy the delightful Mexican flavors combined with the comfort of lasagna!

Helpful Tips for Making the Best Keto Mexican Taco Lasagna

1. Zucchini Substitutes:

If you don’t have zucchini or prefer a different vegetable, you can also use eggplant or yellow squash. These vegetables will provide similar texture and structure while keeping the dish low-carb.

2. Ground Meat Alternatives:

Feel free to use ground turkey, chicken, or pork in place of ground beef. Just make sure to season it well to maintain the taco flavors.

3. Cheese Choices:

If you’re not a fan of cheddar, you can use pepper jack cheese for an added kick, or try a Mexican cheese blend for even more flavor depth.

4. Make Ahead Option:

This dish is perfect for meal prepping. After assembling, you can store the lasagna in the refrigerator for up to 3-4 days or freeze it for up to 3 months. Simply bake it from frozen, though it may need an additional 10-15 minutes in the oven.

5. Low-Carb Taco Seasoning:

If you prefer to make your own seasoning, the homemade taco seasoning can be adjusted to your taste preferences. Feel free to add extra chili powder, cumin, or even some lime zest for a tangy twist.
