Ingredients:

3 cups cooked quinoa (this usually comes from about 1 cup of dried quinoa, so plan accordingly if starting from dry)
1 lb ground beef
2 medium zucchinis (approximately 1.5 to 2 lbs total), chopped into bite-size pieces
1 small yellow onion, finely diced
2 tablespoons olive oil, divided
1 (14.5 oz) can tomato sauce
1 (14.5 oz) can diced tomatoes, drained (draining is key to avoid a watery casserole)
1 tablespoon Italian seasoning (a good blend of herbs like oregano, basil, rosemary, thyme, and marjoram)
1 teaspoon dried oregano
1 teaspoon garlic powder
1 teaspoon dried basil
1 teaspoon sea salt, divided (we’ll use some in the beef mixture and some for seasoning later)
½ teaspoon black pepper
2 cups shredded mozzarella cheese, divided (this will give us a lovely cheesy topping)

Searing the Beef and Aromatics

Begin extract by heating 1 tablespoon of the olive oil in a large skillet or Dutch oven over medium-high heat. Add the ground beef to the hot skillet. Break up the beef with a spoon as it cooks. You want to brown it evenly, aiming for a nice crust on the pieces. This step is crucial for developing flavor. Once the beef is mostly browned, drain off any excess grease. This will prevent your casserole from feeling heavy and oily.
Add the diced yellow onion to the same skillet with the browned beef. Cook, stirring occasionally, until the onion becomes softened and translucent, which should take about 5-7 minutes. The natural sugars in the onion will caramelize slightly, adding another layer of sweetness and depth to the dish.

Building the Flavor Base

Now, it’s time to introduce the seasonings. Sprinkle in the Italian seasoning, dried oregano, garlic powder, dried basil, ½ teaspoon of sea salt, and the black pepper directly over the beef and onion mixture. Stir well to ensure all the spices are evenly distributed. Cook for another minute, allowing the heat to bloom the spices and release their fragrant aromas. This brief toasting of the spices significantly enhances their flavor.
Pour in the tomato sauce and the drained diced tomatoes. Stir everything together to combine. Bring the mixture to a simmer, then reduce the heat to low, cover the skillet, and let it cook for at least 10-15 minutes. This simmering period allows the flavors to meld together beautifully. You’re creating a rich, savory sauce that will coat all the other ingredients. Stir occasionally to prevent sticking.

Incorporating Zucchini and Quinoa

While the sauce is simmering, prepare your zucchinis. Ensure they are washed and chopped into bite-sized pieces. The size of the pieces will affect how tender they become; aim for about ½-inch cubes for a good balance of texture and tenderness.
Add the chopped zucchinis to the simmering beef and tomato mixture. Stir them in gently. If the mixture seems a bit too thick at this point, you can add a tablespoon or two of water or broth to loosen it up. Cover the skillet again and continue to simmer for another 8-10 minutes, or until the zucchini is tender but not mushy. You want it to retain a slight bite.
Finally, stir in the cooked quinoa. Ensure it’s well combined with the beef, tomato, and zucchini mixture. This is where the casserole really starts to come together. The quinoa will absorb some of the delicious sauce, adding substance and a wonderful texture. Taste the mixture at this point and add the remaining ½ teaspoon of sea salt if needed, or adjust other seasonings to your preference.

Assembling and Baking the Casserole

Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish or a similar-sized casserole dish with a little cooking spray or butter.
Spoon the entire beef, zucchini, quinoa, and sauce mixture into the prepared baking dish, spreading it out evenly.
Sprinkle 1.5 cups of the shredded mozzarella cheese evenly over the top of the casserole. Reserve the remaining ½ cup of mozzarella for a final flourish.
Bake for 15-20 minutes, or until the casserole is heated through and the cheese is melted and bubbly. For an extra golden-brown topping, you can switch the oven to broil for the last 1-2 minutes, watching carefully to prevent burning.
Remove the casserole from the oven and immediately sprinkle the remaining ½ cup of mozzarella cheese over the hot surface. The residual heat will melt this cheese into a beautiful, gooey layer.
