Step-by-step preparation for Cheesy Keto Meatball Casserole
Making a cheesy keto meatball casserole is not only simple but also incredibly satisfying. Let’s dive into the preparation steps to guarantee a delicious outcome!
Preheat the Oven
Start by preheating your oven to 400°F (200°C). This is crucial as it helps cook the meatballs evenly, ensuring that they are cooked through while keeping them moist and flavorful. While the oven is heating up, prepare your 9x13 inch casserole dish by lightly spraying it with cooking spray. This will help prevent sticking and make cleanup easier later on.
Mix the Meatball Ingredients
In a large mixing bowl, it’s time to combine all your meatball ingredients. You’ll need:
- 1 pound ground meat (like lean turkey, beef, or chicken)
- 1 pound Italian sausage
- 1 cup shredded mozzarella cheese
- 0.33 cup grated Parmesan cheese
- 1 medium zucchini, shredded
- 1 large egg
- 2 teaspoons each of dried minced onion and garlic
- 2 teaspoons dried basil (or Italian seasoning)
- 1 teaspoon salt
Using your hands or a rubber spatula, mix everything thoroughly until just combined. The zucchini serves as a fantastic hidden veggie, and you may want to check out how to add more low-carb vegetables → Healthline's guide on keto-friendly veggies.
Form and Bake the Meatballs
Now, it’s time to form your meatballs! Scoop out about 24 meatballs using a large cookie scoop for uniformity. Place them evenly in the prepared casserole dish. You’ll want to bake them for around 30 minutes or until they're almost cooked through. This initial baking helps lock in those delicious flavors!
Drain and Add Marinara Sauce
Once the meatballs are baked to perfection, take the casserole dish out of the oven. Carefully drain any excess cooking liquid. This step ensures that your casserole doesn't end up watery. Next, pour 1 cup of sugar-free marinara sauce evenly over the meatballs. This sauce adds all the richness and flavor you want in a cheesy keto meatball casserole, bringing out the best in your ingredients!
Melt the Topping Cheese
To finish things off, sprinkle your meatballs generously with 8 ounces of shredded cheese blend. Pop the casserole back into the oven for another 10-15 minutes or until the cheese is melted and bubbly. If you're looking for a toasty top, consider broiling it for the last 2-3 minutes—just keep a close watch to prevent burning!
There you have it! A beautifully satisfying cheesy keto meatball casserole ready to be served. Enjoy it on its own or pair it with a refreshing salad for a complete meal. Bon appétit!
