Let’s Get Cooking!
Alright, let’s get to the fun part! Here’s how to make this amazing Shrimp Crab Lasagna.
Preheat Your Oven: Turn your oven on to 375°F (190°C).
Prepare Your Noodles: Boil the lasagna noodles according to the package directions (probably around 8-10 minutes), then drain and leave them somewhere to cool off for a few minutes.
Sauté the Seafood: In a large pan over medium heat, warm up your olive oil. Toss in the minced garlic and stir it around until fragrant, about a minute. Then, add in the shrimp and cook until they’ve turned pink, around 3-4 minutes keep an eye on these little guys until they’re no longer see-through. Now, mix in the crab along with a couple pinches of salt, black pepper, and that optional chili flake goodness! Cook for another 2-3 minutes, and then take the pan off the heat.
Make the Cheese Mixture: In a mixing bowl, combine the ricotta, half of the Parmesan cheese, one cup of mozzarella, the chopped parsley, and the heavy cream. Stir until it’s all smooth and blended oh, the smells!
Layer It Up: Grab a 9×13 inch baking pan and smear some Alfredo sauce on the bottom to keep things from sticking. Now, place a layer of noodles down, then spread across a portion of the cheese mixture. Add some of that delicious seafood mix on top, drizzle more sauce, and start the next layer. Keep repeating until you’ve got three layers total, ending with noodles and a nice layer of Alfredo sauce on top.
Add Toppings: Now sprinkle the remaining Parmesan, mozzarella, and breadcrumbs on top. Cover it loosely with foil (this keeps it from browning too fast) and pop it in the oven! Bake for about 25 minutes.
Finish Baking: After 25 minutes, remove the foil and let it bake for another 10-15 minutes until everything is bubbling and golden brown, my favorite part!
Rest Before Serving: Let it rest for about 10 minutes after it’s out of the oven. And if you’re feeling fancy (which you totally should), sprinkle a bit more parsley on top before serving!
