Can I make lasagna soup ahead of time?
Yes. Cool completely and refrigerate for up to 4 days in an airtight container. Reheat gently on the stovetop, adding broth if it thickens. Do not freeze—ricotta topping may separate.
What type of Italian sausage should I use?
Use bulk Italian sausage (not links) for even browning and texture. Choose mild or hot based on your spice preference; the red pepper flakes already add heat.
Can I substitute ricotta with another cheese?
Yes. Use an equal amount of mascarpone, cream cheese softened, or a dollop of sour cream. Ricotta is traditional, but these work as toppings.
How do I prevent lasagna noodles from getting mushy?
Add noodles in the final 10–12 minutes of cooking. Stir occasionally to prevent sticking and clumping. Taste at 10 minutes; al dente is ideal.
Can I use fresh spinach instead of frozen?
Yes. Use 4–5 cups fresh spinach and stir in at the very end; it wilts down quickly. Frozen spinach is pre-wilted, so timing is more forgiving.
