Ingredients:

• 3 cups cooked quinoa (this is roughly equivnon-alcoholic alent to 1 cup of dried quinoa cooked according to package directions)
• 1 pound ground beef
• 2 medium zucchinis (approximately 1.5 to 2 pounds total weight), chopped into roughly ½-inch 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 (draining them helps to prevent the casserole from becoming too watery)
• 1 tablespoon Italian seasoning (this blend typically includes basil, oregano, thyme, rosemary, and marjoram, providing a classic Italian flavor)
• 1 teaspoon dried oregano
• 1 teaspoon garlic powder (for a mellow garlic flavor without the harshness of fresh garlic)
• 1 teaspoon dried basil
• 1 teaspoon sea salt, divided (you’ll use some for the beef mixture and some for seasoning the vegetables, if needed)
• ½ teaspoon black pepper
• 2 cups shredded mozzarella cheese, divided (this will be used for topping and a layer within the casserole for ultimate cheesiness)

Preparing the Flavor Base

Sautéing Aromatics and Browning Beef

1. Begin extract by heating 1 tablespoon of the olive oil in a large skillet or Dutch oven over medium-high heat. Once the oil is shimmering, add your diced yellow onion. Cook, stirring frequently, for about 3-5 minutes, or until the onion has softened and become translucent. This step is crucial for building a foundational flavor for your casserole, as the sweetness of the onions will meld beautifully with the beef.
2. Add the 1 pound of ground beef to the skillet with the softened onions. Break up the meat with your spoon and cook until it’s thoroughly browned. As the beef cooks, you’ll notice it releasing its fat. It’s a good idea to drain off any excess grease at this point to keep the casserole from being too oily. A simple tilt of the pan and careful pouring will do the trick.
3. Once the beef is browned, stir in the garlic powder, dried oregano, dried basil, ½ teaspoon of the sea salt, and the ½ teaspoon of black pepper. Cook for another minute, stirring constantly, until the spices are fragrant. This brief cooking time helps to bloom the spices, intensifying their flavor and aroma before you add the wet ingredients.

Incorporating Vegetables and Building the Casserole

Simmering the Sauce and Prepping the Zucchini

1. To the skillet with the seasoned beef and onions, add the 1 (14.5 ounce) can of tomato sauce and the drained 1 (14.5 ounce) can of diced tomatoes. Stir everything together well. Bring the mixture to a gentle simmer, then reduce the heat to low, cover, and let it cook for about 10-15 minutes. This simmering time allows the flavors to meld together beautifully and creates a rich, saucy base for your casserole.
2. While the beef mixture is simmering, prepare your zucchini. In a separate medium bowl, toss the 2 medium chopped zucchinis with the remaining 1 tablespoon of olive oil and ¼ teaspoon of the sea salt. You can also add the 1 tablespoon of Italian seasoning to the zucchini at this stage if you prefer a more distinct herbaceous flavor directly on the vegetables, or you can stir it into the beef mixture. Ensure the zucchini pieces are evenly coated with oil and salt.

Assembling and Baking the Zucchini Ground Beef Casserole

Layering and Melting the Cheese

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with cooking spray or a little butter to prevent sticking.
2. Now it’s time to assemble your delicious Zucchini Ground Beef Casserole. Spread about half of the cooked quinoa evenly across the bottom of the prepared baking dish. This will form a substantial base for our flavorful beef and vegetable layers.
3. Next, spoon about half of the simmering ground beef and tomato mixture over the layer of quinoa. Don’t worry if it’s not perfectly even; it will settle during baking. Then, carefully arrange about half of the seasoned, chopped zucchini over the beef layer. You want to try and distribute them relatively evenly so each bite gets a good mix of everything.
4. Sprinkle about 1 cup of the shredded mozzarella cheese evenly over the zucchini layer. This cheesy layer will create a delightful binding and an irresistible gooey texture once melted.
5. Repeat the layering process: add the remaining cooked quinoa over the mozzarella cheese. Then, spoon the remaining ground beef mixture on top of the quinoa, followed by the rest of the chopped zucchini. Finally, sprinkle the remaining 1 cup of shredded mozzarella cheese evenly over the very top of the casserole. This final layer of cheese is what will become golden brown and bubbly in the oven, creating that classic casserole appeal.
6. Cover the baking dish loosely with aluminum foil. The foil helps to steam the ingredients and ensure the zucchini is tender without the cheese browning too quickly. Bake for 25 minutes.
7. After 25 minutes, carefully remove the aluminum foil and continue to bake for another 15-20 minutes, or until the cheese is melted, bubbly, and lightly golden brown, and the casserole is heated through. You’ll know it’s ready when you see delicious bubbling around the edges and the cheese on top has achieved that perfect golden hue.
