Tips for the Best Lasagna

  • Use fresh cheese. Grating mozzarella and Parmesan yourself gives the best melt and flavor.
  • Don’t skimp on sauce. A generous béchamel keeps every layer moist and creamy.
  • Add extra veggies. Zucchini, bell peppers, or roasted squash all make delicious additions.
  • Make ahead. Assemble up to a day in advance and refrigerate before baking.

Variations

  • Gluten-Free: Use gluten-free lasagna noodles and flour for the béchamel.
  • Vegan: Swap butter and milk for plant-based alternatives, and use dairy-free cheese.
  • Spicy Twist: Add red pepper flakes or sauté onions with the mushrooms for extra depth.

Storage & Reheating

  • Fridge: Store leftovers in an airtight container for up to 3–4 days.
  • Freezer: Assemble, wrap tightly, and freeze for up to 3 months. Bake from frozen at 375°F for 60–70 minutes, uncovering for the last 15 minutes.
  • Reheating: Microwave slices for 1–2 minutes or bake covered at 350°F until warmed through.
