Ingredients You’ll Need
- 450 g (16 oz) package uncooked rotini pasta
- 1 jar (24–25 oz) marinara sauce
- 3 cups water
- 14 oz package fully-cooked miniature (cocktail-size) meatballs, thawed
- 2 cups shredded mozzarella or Italian blend cheese
- Optional garnish: grated Parmesan and fresh chopped herbs like basil or parsley
Step-By-Step Instructions
- Preheat your oven to 425 °F (220 °C).
- Assemble the casserole: In a greased 9×13-inch baking dish, mix uncooked rotini, marinara sauce, water, and thawed meatballs. Stir gently to combine and press down so the pasta is submerged.
- Bake covered with foil for 35 minutes.
- Stir and check pasta: Remove foil, stir gently, and test a noodle. If it’s still too firm, cover again and bake another 5–10 minutes until al dente.
- Add cheese: Sprinkle the shredded mozzarella on top, then return uncovered to the oven for 5–10 minutes, until the cheese is melted and bubbly.
- Garnish: Top with grated Parmesan and fresh herbs if desired—extra color, flavor, and warmth.
Helpful Notes & Tips
- Versatile pasta: No rotini? Use penne, elbows, or similar-shaped short pasta with about the same cooking time.
- Quality sauce matters: Since there are so few ingredients, a flavorful marinara makes all the difference.
- Thawing meatballs: Be sure they’re fully thawed before assembling—overnight in the fridge works great.
- Check your oven and pan type: Glass and ceramic dishes might take a bit longer to cook than metal pans.
- Storage: Refrigerate leftovers in an airtight container for 3–4 days. Reheat portions in the microwave or oven. Freezing isn’t recommended—pasta texture suffers.
Recipe Variations
- Swap the meatballs: Use turkey, beef, chicken, or Italian-style meatballs to match your family’s favorite flavors.
- Add herbs & seasonings: Stir in 2 tsp Italian seasoning, a pinch of garlic powder, onion powder—or red pepper flakes for a little kick.
- Make it lighter: Use half the cheese and add a sprinkle of nutritional yeast or omit cheese entirely and finish with a drizzle of olive oil before serving.
- Go veggie-rich: Layer in spinach, mushrooms, or zucchini around the casserole before baking for added veggies and wholesome goodness.
Serving Suggestions
- Bread on the side: Serve with garlic bread, focaccia, or breadsticks to scoop up that cheesy sauce.
- A crisp balance: A simple Caesar salad or mixed greens with vinaigrette adds a refreshing touch.
- Veggie companions: Roasted broccoli, zucchini, or yellow squash add color, freshness, and texture to the table.
