Ingredients:

3 cups cooked quinoa (this is about 1 cup of dried quinoa cooked according to package directions)
1 lb ground beef
2 medium zucchinis (approximately 1.5 to 2 pounds total), chopped into bite-size pieces
1 small yellow onion, finely diced
2 tablespoons olive oil, divided
1 (14.5 ounce) can tomato sauce
1 (14.5 ounce) can diced tomatoes, drained
1 tablespoon Italian seasoning
1 teaspoon dried oregano
1 teaspoon garlic powder
1 teaspoon dried basil
1 teaspoon sea salt, divided
½ teaspoon black pepper
2 cups shredded mozzarella cheese, divided

Preparing the Zucchini Ground Beef Casserole

Sautéing the Aromatics and Beef

Begin extract by preparing your vegetables. Wash and chop your two medium zucchinis into bite-size pieces, roughly ½-inch cubes. This size ensures they cook through evenly in the casserole without becoming mushy. Next, finely dice your small yellow onion. Having the onion diced small will allow it to soften and meld beautifully with the ground beef.

Heat 1 tablespoon of the olive oil in a large skillet or Dutch oven over medium-high heat. Once the oil is shimmering, add the diced yellow onion. Sauté the onion for about 3-5 minutes, stirring occasionally, until it becomes translucent and starts to soften. This process is called sweating the onions and it brings out their natural sweetness.

Now, add the 1 pound of ground beef to the skillet. Break up the ground beef with a spoon and cook it until it’s browned all over. You’re looking for no pink remaining. As the beef cooks, you can carefully drain off any excess grease from the skillet. This step helps prevent the casserole from becoming too oily.

Building the Flavor Base

Once the ground beef is nicely browned and any excess grease is drained, it’s time to add the seasonings. Sprinkle in the Italian seasoning, dried oregano, garlic powder, and dried basil. Add ½ teaspoon of the sea salt and the ½ teaspoon of black pepper. Stir everything together well to ensure the spices are evenly distributed throughout the beef and onion mixture. Cook for another minute or two, stirring constantly, allowing the fragrant spices to toast slightly and release their full flavor.

Next, pour in the 1 (14.5 ounce) can of tomato sauce and the drained 1 (14.5 ounce) can of diced tomatoes. Stir to combine everything. The tomato sauce will act as the binder for our casserole, while the diced tomatoes add a pleasing texture and bursts of tomato flavor. Bring the mixture to a gentle simmer, then reduce the heat to low, cover the skillet, and let it cook for about 10 minutes. This simmering period allows the flavors to meld together beautifully and for the sauce to thicken slightly.

Incorporating the Zucchini and Quinoa

While the beef mixture is simmering, prepare your zucchinis if you haven’t already. Add the chopped zucchinis to the skillet with the beef and tomato mixture. Stir gently to incorporate them. Cover the skillet again and let it simmer for another 5-7 minutes, or until the zucchinis are tender-crisp. You don’t want them to be completely soft at this stage, as they will continue to cook in the oven.

Now, add the 3 cups of cooked quinoa to the skillet. Gently stir the quinoa into the beef, vegetable, and tomato mixture. Make sure the quinoa is evenly distributed. The quinoa will absorb some of the sauce and act as a wonderful base for our casserole.

Assembling and Baking the Casserole

Preheat your oven to 375°F (190°C). While the oven is preheating, lightly grease a 9×13 inch baking dish with a little bit of the remaining olive oil. This prevents the casserole from sticking.

Pour the entire contents of the skillet into the prepared baking dish. Spread the mixture evenly using a spatula. Now comes the cheesy goodness! Sprinkle 1 cup of the shredded mozzarella cheese evenly over the top of the casserole. This first layer of cheese will melt and create a gooey, delicious topping.

Finally, sprinkle the remaining 1 cup of shredded mozzarella cheese over the top of the first layer. Ensure an even distribution for maximum cheesy coverage.

Place the baking dish in the preheated oven. Bake for 20-25 minutes, or until the cheese is melted, bubbly, and lightly golden brown. The edges of the casserole should also be starting to bubble. If you prefer a more deeply browned cheese topping, you can briefly place the casserole under the broiler for the last 1-2 minutes of baking, watching it very carefully to prevent burning. Once baked to perfection, carefully remove the casserole from the oven and let it rest for about 5-10 minutes before serving. This resting period allows the casserole to set up slightly, making it easier to serve and preventing it from being too runny.
