How to Make Penne Lasagna
- Cook penne for 4 minutes to soften them. They should be very al dente. In a bowl, combine the spaghetti sauce with 1 1/2 cups of ricotta cheese. Mix until thoroughly blended.
- Add drained penne and mix thoroughly. Put mixture in a buttered casserole dish and bake at 350º for 1 hour.
- After 1 hour, take out and top with shredded mozzarella and cook an additional 10 minutes or until cheese is melted and bubbly.
