Healthy Twists on a Classic
If you want to make it healthier, consider using whole wheat lasagna noodles. You can also mix in extra vegetables, like zucchini or bell peppers, for added nutrition. For a lighter cheese option, use part-skim ricotta and mozzarella.
Serving Suggestions From My Table
I love serving my lasagna with a side salad and garlic bread. The freshness of the salad balances the richness of the lasagna. You can also pair it with a nice red wine if you’re feeling fancy!
Getting It Just Right
Make sure to let your lasagna rest for a few minutes before cutting. This helps the layers set, making it easier to serve. If you want a deeper flavor, you can let the mushroom filling cool and then mix in some fresh herbs.
