1 tbsp olive oil
1 small onion, diced

1/2 tsp kosher salt
1/2 tsp black pepper
1 28 ounce can diced tomatoes, drained

How to Make Ground Beef Zucchini Casserole

Step 1: Prepare the Zucchini

Slice the zucchini into 1/2 rounds. Put the rounds in a sieve or colander over the sink or a bowl and sprinkle with salt, tossing to coat.
Allow the salted zucchini to sit for 15 minutes to draw out excess moisture.
Rinse well under cold water to remove the excess salt. Pat dry with paper towel.

Step 2: Cook the Beef Mixture

Heat olive oil in a large skillet over medium high heat.
Add diced onions and cook until they begin to soften, about 2 minutes.
Add minced garlic and lean ground beef to the skillet, breaking it up with a spoon.
Cook while stirring often until the meat is browned with no trace of pink, about 5 minutes.
Stir in drained diced tomatoes, Italian seasoning, kosher salt, and black pepper. Remove from heat.

Step 3: Assemble the Casserole

Preheat your oven to 350°F (175°C).
In an 8×8 baking dish, spread half of the ground beef mixture evenly across the bottom.
Layer half of the zucchini slices over the meat mixture.
Sprinkle half of the shredded mozzarella cheese over the zucchini slices.
Repeat these layers with the remaining ground beef mixture, zucchini slices, and cheese.

Step 4: Bake and Serve

Bake in the preheated oven for 20 to 25 minutes until cheese is melted and beginning to brown.
Allow casserole to rest for 10 minutes before serving.

Common Mistakes to Avoid

Not salting the zucchini – Failing to salt the zucchini can lead to a watery casserole. Always salt and let it sit to draw out excess moisture.

Overcooking the cheese – If you bake the casserole too long, the cheese may become rubbery. Keep an eye on it and remove it when the cheese is bubbly and golden.
Ignoring ingredient quality – Using low-quality ingredients can affect taste. Opt for fresh zucchini and good-quality ground beef for the best results.
