Ingredients You’ll Need

To make this Keto Crockpot Zucchini Lasagna, you’ll need a handful of simple, wholesome ingredients.

For the Zucchini “Noodles”

• Zucchini – Fresh, medium-sized zucchini, thinly sliced lengthwise to mimic lasagna noodles.
• Salt – Helps draw out excess moisture to prevent a watery lasagna.

For the Meat Sauce

• Ground beef or Italian sausage – Provides a rich, hearty base for the sauce.
• Onion & garlic – Adds depth and aroma to the sauce.
• Sugar-free marinara sauce or crushed tomatoes – A keto-friendly option to keep the sauce flavorful without unnecessary sugars.
• Italian seasoning, salt, and pepper – Enhances the overall taste with a classic Italian flavor profile.

For the Cheese Layers

• Ricotta cheese or cottage cheese – Creates a creamy and rich texture between the layers.
• Egg – Helps bind the cheese mixture, making it thicker and more structured.
• Shredded mozzarella cheese – Adds that irresistible gooey and cheesy pull.
• Grated Parmesan cheese – Brings a nutty, salty depth to the dish.

Step-by-Step Instructions to Make Keto Crockpot Zucchini Lasagna

Step 1: Prepare the Zucchini Noodles

Thinly slice the zucchini lengthwise using a mandoline or a sharp knife. Lay the slices out on a paper towel and sprinkle them lightly with salt.

Let them sit for 10–15 minutes to draw out excess moisture. Pat them dry with another paper towel to prevent a watery lasagna.

Step 2: Cook the Meat Sauce

In a large skillet over medium heat, brown the ground beef or Italian sausage until fully cooked.

Add the chopped onion and minced garlic, cooking until fragrant and soft. Drain any excess grease.

Stir in the sugar-free marinara sauce and season with Italian seasoning, salt, and pepper.

Let the sauce simmer for about 10 minutes, allowing the flavors to meld together.

Step 3: Prepare the Cheese Mixture

In a medium bowl, mix ricotta cheese, egg, and grated Parmesan. Stir until well combined.

This mixture will add a creamy, rich texture to the lasagna layers.

Step 4: Assemble the Lasagna in the Crockpot

Lightly grease the crockpot to prevent sticking. Begin layering:

1. Spread a thin layer of meat sauce on the bottom.
2. Place a layer of zucchini slices over the sauce.
3. Spread a portion of the ricotta cheese mixture on top.
4. Sprinkle shredded mozzarella cheese over the ricotta layer.
5. Repeat the layers until all ingredients are used, finishing with a final layer of mozzarella cheese.

Step 5: Cook in the Crockpot

Cover and cook on low for 4–5 hours or high for 2–3 hours.

The slow cooking process allows the flavors to meld beautifully while keeping the zucchini tender but not mushy.

Once done, let the lasagna sit for 10–15 minutes before serving. This helps it firm up, making it easier to slice and serve.

Tips for the Best Keto Zucchini Lasagna

Prevent a Watery Lasagna

Zucchini naturally contains a lot of water, which can make your lasagna too soupy. To avoid this:

• Salt and drain the zucchini – Let the slices sit with salt for 10–15 minutes, then pat them dry.
• Pre-grill or bake the zucchini – Lightly grilling or baking the slices for a few minutes before layering can remove extra moisture.
• Use a thick meat sauce – Simmer your sauce until it thickens to prevent excess liquid.

Layering for the Best Texture

To ensure a well-structured lasagna:

• Don’t overlap zucchini slices too much, as this can make them release more moisture.
• Spread the ricotta mixture evenly to create a creamy texture in every bite.
• Finish with a generous layer of mozzarella on top for a perfect golden, bubbly finish.

Adjusting for Personal Preference

• Use Italian sausage instead of ground beef for a spicier, more flavorful sauce.
• Mix in spinach or mushrooms for extra nutrients and texture.
• Add red pepper flakes if you like a bit of heat.

Storage & Reheating Instructions

Storing Leftovers

This lasagna stores beautifully and even tastes better the next day.

Frequently Asked Questions

Salting and patting the zucchini dry is key. You can also pre-bake or grill the slices for a few minutes to remove excess moisture.
