You Will Love This Taco Casserole
The zucchini and cheese crust is so delicious and adds amazing flavor.
Got lots of zucchini growing in your garden? I do! In fact, I accidentally let a zucchini grow too large so I used it in this recipe and it made the perfect 4 cups shredded zucchini.
This is a perfect casserole if you are a mixed diet household. While this is a low carb and keto-friendly recipe it should work for almost everyone in your house, whether they are following a ketogenic diet or not. This will make your life easier.
You can make this casserole ahead of time by baking and freezing, or you can assemble it and keep it in the fridge the day before you want to bake this. You can also bake the casserole and eat on it for several days for lunch.

Step by Step Instructions
Make and Bake The Zucchini Crust
Preheat oven to 400ºF
Drain shredded zucchini in a colander, sprinkle with salt, and let stand for 10 to 15 minutes. Squeeze out excess moisture.
In a large bowl, combine, zucchini, eggs, half of cheddar, and pepper jack cheese.
Spray a 13 x 9" casserole dish with nonstick spray. Press mixture into the bottom of the dish and bake for 20 minutes.
Prepare Taco Meat
In a skillet over medium-high heat, brown ground beef until no longer pink. Drain fat. Add taco seasoning mix and 3/4 cup water. Cook until liquid is absorbed.
Add sour cream and salsa to the meat and stir until combined.
Spread the meat mixture evenly over the top of the zucchini crust. Top with the remaining half of cheeses.
Bake until cheese is bubbly, approximately 20 minutes.
The casserole can be topped with your favorite taco toppings such as shredded lettuce, diced tomato, green onion, olives, and sliced avocado. Serve with additional sour cream and salsa.
- Always use freshly grated cheese. Pre-grated cheese that comes from packages is coated to keep it from sticking. This coating also prevents the cheese from melting.
- Make sure that your grated zucchini has had the moisture thoroughly removed from it. Sprinkling the salt over the zucchini while it sits draws out the moisture. Use your hands to gently squeeze the zucchini to wring the moisture out. If it still seems moist you can dab the zucchini with a paper towel.
How can I lower the fat in this recipe?
You can lower the fat in this recipe by using lower-fat cheeses, and by substituting a fat-free sour cream of regular sour cream. You can also use leaner ground beef, or substitute a lower fat ground turkey or chicken. Enjoy!
Can I freeze zucchini ground beef taco casserole?
Yes, this taco casserole is freezable! Bake and cool the casserole. Cover and freeze. To reheat, partially thaw the casserole overnight in your refrigerator. Remove from the fridge 30 minutes prior to baking.
Note that if you have topped the casserole with fresh vegetables such as shredded lettuce, tomato, green onion, these cannot be frozen. You will need to remove it before freezing.
Bake the casserole (uncovered) at 350º for 30 minutes or until heated through.
How long will taco casserole keep in the refrigerator?
Mexican taco casserole will keep for 3 to 4 days in the refrigerator after it has been baked. This casserole makes GREAT leftovers!
