Ingredients:

3 cups cooked quinoa (this is about 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 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

Cooking the Ground Beef and Aromatics

Step 1: Brown the Ground Beef and Sauté the Onion

Let’s get started by building a flavorful base for our Zucchini Ground Beef Casserole. Heat 1 tablespoon of olive oil in a large skillet or Dutch oven over medium-high heat. Add the 1 pound of ground beef to the hot skillet. Break it apart with a spoon or spatula and cook until it’s nicely browned and no pink remains. This usually takes about 6-8 minutes. Once the beef is cooked through, use a slotted spoon to transfer it to a bowl, leaving any rendered fat in the skillet. If there’s an excessive amount of fat, you can carefully drain some of it off, but leave about 1-2 tablespoons for sautéing the vegetables.

Now, add the finely diced small yellow onion to the same skillet with the remaining fat. Reduce the heat to medium and cook the onion, stirring occasionally, until it becomes softened and translucent. This will take around 5-7 minutes. The sweetness of the softened onion will meld beautifully with the beef and other ingredients. If the skillet seems a bit dry, you can add the remaining 1 tablespoon of olive oil at this stage to help the onions sauté evenly.

Incorporating the Vegetables and Seasonings

Step 2: Add Zucchini and Tomatoes

With your onions softened and the ground beef set aside, it’s time to introduce the star of our Zucchini Ground Beef Casserole: the zucchini! Add the chopped medium zucchinis (about 1.5 to 2 pounds total) to the skillet with the sautéed onions. Stir everything together and cook for about 5-7 minutes, or until the zucchini begin extracts to soften slightly but still retains a bit of its firmness. We don’t want mushy zucchini, so keep an eye on it.

Next, pour in the contents of the 1 (14.5 ounce) can of tomato sauce. This will provide a rich, saucy base. Add the drained 1 (14.5 ounce) can of diced tomatoes. The diced tomatoes will add bursts of flavor and texture to the casserole. Stir both the tomato sauce and diced tomatoes into the zucchini and onion mixture, ensuring everything is well combined.

Building the Flavor Profile

Step 3: Season the Mixture

Now we’ll infuse our Zucchini Ground Beef Casserole with layers of delicious flavor. To the skillet, add the Italian seasoning, dried oregano, garlic powder, and dried basil. These dried herbs are essential for that classic savory taste. Also, add ½ teaspoon of the sea salt and the ½ teaspoon of black pepper at this point. Stir all the seasonings into the vegetable and tomato mixture. It’s important to taste as you go and adjust the salt and pepper if needed, especially after the ingredients have had a chance to meld.

Return the browned ground beef to the skillet. Stir it thoroughly into the zucchini and tomato mixture. Allow the mixture to simmer gently over medium-low heat for about 10-15 minutes. This simmering time is crucial for the flavors to develop and meld together, and for the zucchini to become tender-crisp. The sauce should thicken slightly during this process.

Assembling and Baking the Casserole

Step 4: Combine with Quinoa and Cheese

Preheat your oven to 375°F (190°C). Now it’s time to assemble our Zucchini Ground Beef Casserole. In a large mixing bowl, combine the cooked quinoa (which should be about 3 cups) with the meat and vegetable mixture from the skillet. Gently fold them together until the quinoa is evenly distributed throughout the savory mixture.

Add 1 cup of the shredded mozzarella cheese to the bowl with the quinoa and meat mixture. Stir it in gently until it’s incorporated. The cheese will add a lovely creaminess and bind everything together beautifully. Taste the mixture one last time and adjust the remaining ½ teaspoon of sea salt if you feel it needs it. Remember, the mozzarella will add a bit of saltiness too, so be mindful.

Step 5: Bake to Golden Perfection

Pour the entire mixture into a greased 9×13 inch baking dish or a similar-sized casserole dish. Spread it out evenly. Sprinkle the remaining 1 cup of shredded mozzarella cheese evenly over the top of the casserole. This cheesy topping is going to get wonderfully golden brown and bubbly in the oven, creating that irresistible crust.

Place the baking dish on a baking sheet (this helps catch any potential drips and makes it easier to get in and out of the oven). Bake for 25-30 minutes, or until the cheese is melted, golden brown, and bubbly. The casserole should be heated through. If you prefer a more browned and crispy top, you can briefly place the casserole under the broiler for the last 1-2 minutes of baking, watching it very closely to prevent burning. Let the Zucchini Ground Beef Casserole rest for about 5-10 minutes before serving. This resting period allows the casserole to set slightly, making it easier to scoop and serve.

Conclusion:

And there you have it – your delicious and satisfying Zucchini Ground Beef Casserole is ready to be enjoyed! This recipe is a fantastic weeknight meal, offering a perfect balance of savory ground beef, tender zucchini, and creamy, cheesy goodness. It’s a hearty dish that proves healthy eating can also be incredibly flavorful and comforting. We hope you’ve enjoyed making it as much as we love eating it!

For serving suggestions, this Zucchini Ground Beef Casserole is wonderful on its own, but it also pairs beautifully with a simple side salad or some crusty bread for soaking up any extra sauce. Feel free to get creative with variations! You could swap out the ground beef for ground turkey or chicken, add a pinch of red pepper flakes for a little heat, or mix in other vegetables like diced bell peppers or mushrooms. Don’t be afraid to experiment with different cheeses too – mozzarella, cheddar, or a Monterey Jack blend would all be excellent choices. Dive in and savor every bite!

Frequently Asked Questions:

Q: Can I make this Zucchini Ground Beef Casserole ahead of time?

Absolutely! This Zucchini Ground Beef Casserole is a great make-ahead dish. You can assemble it completely, cover it tightly with plastic wrap and then foil, and refrigerate it for up to 2 days. When you’re ready to bake, remove the plastic wrap and bake as directed, possibly adding a few extra minutes to ensure it’s heated through. You can also freeze the unbaked casserole for up to 3 months. Thaw it in the refrigerator overnight before baking.

Q: My zucchini seems watery after baking. How can I prevent this?

A common issue with zucchini is its high water content. To minimize this in your Zucchini Ground Beef Casserole, it’s recommended to salt the sliced or shredded zucchini and let it sit in a colander for about 20-30 minutes before adding it to the recipe. This draws out excess moisture. Gently press the zucchini to squeeze out more water before incorporating it into the dish. This step makes a significant difference in the final texture.
