FAQS:

What should I serve with meatball casserole?

Meatball casserole is a hearty dish, so you can complement it with sides that balance out the richness. Here are a few ideas:

1. Gluten Free Garlic Bread or Breadsticks: A classic, these are perfect for soaking up any sauce from the casserole.
2. Green Salad: A light, crisp salad with a simple vinaigrette or lemon dressing adds freshness and cuts through the richness of the casserole.
3. Roasted Vegetables: Roasted broccoli, zucchini, or Brussels sprouts are great options for a warm, savory side.
4. Sautéed Spinach or Kale: Lightly sautéed greens with garlic and olive oil bring a nutritious, earthy element to the meal.

What substitutions can I make in meatball casserole?

Here are some substitutions you can make in a meatball casserole, depending on your preferences or dietary restrictions:

Meatballs:

• Ground turkey or chicken instead of beef/pork for a leaner option.
• Lentils, chickpeas, or black beans as a plant-based substitute.
• Store-bought veggie meatballs if you’re short on time or want a vegetarian option.

Cheese:

• Mozzarella can be replaced with cheddar, Swiss, or provolone for a different flavor.
• For a dairy-free alternative, use plant-based cheese like cashew cheese or dairy-free mozzarella.

Pasta:

• Replace with zucchini noodles or spaghetti squash for a low-carb option.

Sauce:

• Instead of tomato sauce, you can try alfredo sauce, pesto, or even a butter and garlic sauce for a creamy twist.
• Use homemade marinara to control the ingredients and reduce sodium.

These ideas allow you to customize the casserole to fit different dietary needs or flavor preferences!

How do I store meatball casserole?

To store meatball casserole properly and keep it fresh, follow these steps:

1. Refrigerating (if you plan to eat within 3-4 days):

• Cool it down: Allow the casserole to cool to room temperature.
• Portion it: You can either store it in one large airtight container or divide it into smaller portions for easier reheating.
• Cover it: Use airtight containers or tightly wrap the casserole dish with plastic wrap or aluminum foil.
• Refrigerate: Store in the refrigerator for up to 3-4 days.

2. Freezing (if storing for longer):

• Cool completely: Let the casserole cool to room temperature.
• Portion as needed: Divide it into individual servings or freeze the whole casserole, depending on your needs.
• Wrap well: Use freezer-safe containers, or wrap the casserole tightly with plastic wrap followed by a layer of aluminum foil. This will help prevent freezer burn.
• Label and date: Mark the date on the container, and it can be frozen for up to 2-3 months.

3. Reheating Instructions:

• From fridge: Reheat in the oven at 350°F (175°C) for about 20-25 minutes until heated through, or in the microwave if in smaller portions.  Have some extra spaghettie sauce on hand to top it off since the pasta will have absorbed the rest.
• From freezer: If frozen, let it thaw overnight in the fridge, then reheat as above. For reheating from frozen, bake at 350°F (175°C) for 40-45 minutes, covered with foil, until heated through.
