This delightful dish combines the best of both worlds: the comforting layers of lasagna and the delicate flavors of crab meat. With a rich blend of ricotta cheese, mozzarella cheese, and parmesan cheese, this spaghetti lasagna is elevated by the addition of spinach for a Florentine twist. Perfect for a special dinner or a cozy family meal, this recipe is sure to impress.
If you don't usually have crab meat or ricotta cheese in your pantry, you might need to make a trip to the supermarket. Fresh crab meat can often be found in the seafood section, while ricotta cheese is typically located near other dairy products. Make sure to also pick up some spinach if you don't have any on hand.

Technique Tip for This Recipe
When layering your spaghetti lasagna, ensure that each layer is evenly distributed to achieve a balanced flavor and texture in every bite. For the ricotta mixture, use a spatula to spread it smoothly over the spaghetti. This helps to create a uniform layer that will meld beautifully with the crab meat and spinach. Additionally, when adding the mozzarella and parmesan cheese on top, make sure to cover the entire surface to achieve that perfect golden and bubbly finish.

How to Store or Freeze This Dish
Allow the spaghetti lasagna florentine with crab to cool completely at room temperature before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the lasagna to an airtight container. Refrigerate for up to 3-4 days. When ready to enjoy, reheat in the oven at 350°F (175°C) for about 20 minutes or until heated through.
For freezing, cut the lasagna into individual portions. Wrap each portion tightly in plastic wrap, then in aluminum foil to prevent freezer burn. Place the wrapped portions in a freezer-safe bag or container. Label with the date and contents. Freeze for up to 2-3 months.
To reheat from frozen, remove the plastic wrap and foil. Place the lasagna in an oven-safe dish. Cover with foil and bake at 375°F (190°C) for 45-60 minutes, or until heated through. For a crispy top, remove the foil during the last 10 minutes of baking.
If you prefer to use a microwave, place a portion of the frozen lasagna on a microwave-safe plate. Cover with a microwave-safe lid or another plate. Microwave on medium power for 6-8 minutes, checking halfway through. Continue microwaving in 1-2 minute increments until thoroughly heated.
To maintain the best texture and flavor, avoid reheating the lasagna multiple times. Instead, reheat only the portions you plan to consume immediately.
For an added touch of freshness, sprinkle some extra parmesan cheese or fresh herbs like basil or parsley on top before serving.
