Step 4: Cook the Lasagna

3. Turn off the heat and let rest for 10 minutes before serving.
Tips for Success
• Use a high-quality marinara sauce like Rao’s for the best flavor.
• Add extra veggies: You can layer in chopped spinach, mushrooms, or zucchini for added nutrition.
• For more spice, use hot Italian sausage instead of ground beef.
Storage Options
• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Reheat: Warm in the microwave or on low heat in the slow cooker until heated through.
• Freezer: Freeze individual portions for up to 2 months. Thaw overnight in the fridge before reheating.
