Ingredients

  • 1 1/2 cups water
  • 2 jars (15 1/2 oz. each) spaghetti sauce
  • 1 (16 oz.) box lasagne noodles
  • 1 (15 oz.) container Ricotta cheese
  • 8 oz. Mozzarella cheese
  • 1/2 cup grated Parmesan cheese

Instructions

  1. Combine 1 1/2 cups water with spaghetti sauce in a bowl.
  2. Cover the bottom of a sprayed 13 x 9 x 2-inch baking dish with 1 1/2 cups of sauce.

Tips & Substitutions

To enhance flavor, consider adding Italian seasoning or fresh basil to the sauce mixture. If you don’t have Ricotta cheese, cottage cheese makes a great substitute. For a lighter version, use whole wheat lasagna noodles or skip the cheese layer altogether. This dish is a fantastic way to use up any leftover vegetables, similar to what you might find in Stuffed Sea Shells.

Serving Suggestions

Serve the lasagna hot, garnished with fresh parsley or basil. Pair it with a simple green salad and garlic bread for a complete meal. This dish also pairs beautifully with Italian recipes like Pasta With Primavera Sauce, making it perfect for family gatherings or potlucks.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave for 1-2 minutes or cover the entire dish with foil and warm in a 350°F oven until heated through, about 20 minutes. This helps maintain the moisture of the lasagna.
