About this Recipe
Craving classic spaghetti and meatballs but looking for a lighter, veggie-packed twist? This Spaghetti Squash Meatball Casserole delivers all the comforting flavors you love with a nutritious boost, making it a new family favorite.
This casserole ingeniously swaps traditional pasta for tender spaghetti squash strands, offering a naturally gluten-free base that’s rich in nutrients. Packed with savory lean ground beef meatballs and a generous helping of collard greens and spinach, it’s a clever way to enjoy a hearty meal with more hidden vegetables without sacrificing taste.
Imagine fork-tender strands of spaghetti squash perfectly complementing rich, seasoned lean ground beef meatballs, infused with aromatic fennel seed, coriander, basil, and oregano. Each bite brings together the bright tang of chopped tomatoes and a classic pasta sauce, the creamy smoothness of reduced-fat ricotta, and the savory depth of the meat, all blanketed under gooey, melted part-skim mozzarella. You'll find a delightful contrast between the hearty meat and the subtle sweetness of the squash, with the added benefit of collard greens and spinach woven throughout for a truly wholesome and satisfying experience.
While delicious as is, you can easily adapt this casserole. Consider swapping the lean ground beef for ground turkey or chicken for a different flavor profile. If collard greens aren't your preference, other hearty greens like kale or Swiss chard would also work beautifully. You could also experiment with adding a pinch of red pepper flakes to the meatballs for a touch of heat.
This hearty Spaghetti Squash Meatball Casserole is perfect for a cozy family dinner or a comforting weeknight meal. It's a complete meal on its own, offering robust flavors that satisfy.
