A creamy, cheesy Tuscan sausage pasta bake loaded with Italian sausage, sundried tomatoes, baby spinach, and Parmesan — simmered on the stovetop, then baked under a bubbling layer of melted mozzarella until golden and irresistible.
Keep the sauce looser than you think before baking — the oven reduces it further and the pasta continues absorbing liquid. Don’t skip the 10-minute rest; it allows the casserole to set for cleaner slices. Sweet or hot sausage both work beautifully. Leftovers reheat well with a splash of broth to loosen the sauce.
