Step‑by‑Step Instructions for Baked Crab Pasta
Step 1: Prep Ingredients
Begin by preparing your ingredients for the Baked Crab Pasta. Dice the onion and bell pepper into small, uniform pieces for even cooking. Next, grate both the Swiss and cheddar cheese, ensuring you have a delightful mix ready to melt into your creamy casserole. These steps will make the cooking process smooth and efficient, so everything is at your fingertips.
Step 2: Cook Pasta
In a large pot, bring salted water to a boil and add the 16 oz of Barilla Penne pasta. Cook the pasta just until it’s al dente—aim for about 2 minutes less than the package instructions, so it retains a slight bite. Once cooked, drain the pasta thoroughly in a colander, letting it sit for a moment to remove excess moisture, ensuring it holds up in the casserole.
Step 3: Sauté Vegetables
Now, heat 4 tablespoons of unsalted butter in a large skillet over medium heat. Once melted, add the diced onion and bell pepper, and sauté for about 5–7 minutes, or until the vegetables become soft and translucent. You should see a lovely golden hue in your onions—this means they’re ready to bring sweetness and flavor to your baked crab pasta.
Step 4: Flavor the Mix
Next, add 3/4 teaspoon of oregano, 3/4 teaspoon of garlic powder, 1/2 teaspoon of salt, 1/2 teaspoon of pepper, and 1/4 teaspoon of smoked paprika to the sautéed vegetables. Stir these aromatic spices into the mix and cook for an additional 30 seconds until fragrant. The delightful aroma of the herbs will elevate your Baked Crab Pasta to new heights.
Step 5: Combine Ingredients
In a large mixing bowl, gently combine the drained pasta, sautéed vegetables, 16 oz of crab meat, and 14 oz of sour cream. Use a spatula to mix carefully so as not to break apart the crab meat. This creamy blend will create a delicious foundation for your baked crab pasta casserole, ensuring every bite is packed with flavor and hearty texture.
Step 6: Transfer to Baking Dish
Preheat your oven to 350°F (175°C) while you transfer the mixture into a greased 9×13 inch baking dish. Spread it out evenly, ensuring an even distribution throughout the pan. Then, sprinkle the grated Swiss and cheddar cheese generously over the top, creating a luscious cheese blanket that will melt beautifully as it bakes to golden perfection.
Step 7: Bake
Place the dish in the preheated oven and bake for about 20 minutes. Keep an eye on the casserole, as you want the cheese to melt and develop a light golden color. This step ensures that all the flavors meld together beautifully, resulting in a comforting and gooey Baked Crab Pasta that will have everyone eagerly anticipating dinner.
Step 8: Rest & Serve
After baking, remove the casserole from the oven and let it rest for 2–3 minutes to set slightly. This will make serving easier. Once rested, chop some green onions to sprinkle on top, brightening the dish visually and adding a lovely fresh flavor. Scoop generous portions and prepare for compliments on your delightful Baked Crab Pasta!

Storage Tips for Baked Crab Pasta
Fridge: Store leftover Baked Crab Pasta in an airtight container for up to 3 days to maintain its creamy texture and flavor.
Freezer: For longer storage, wrap the casserole tightly in plastic wrap and aluminum foil, or place it in a freezer-safe container. It can be frozen for up to 2 months.
Reheating: Reheat the casserole in the oven at 350°F for 20-25 minutes until heated through, or microwave individual portions for 2-3 minutes, adding a splash of water to retain moisture if needed.
Make Ahead Options
This Baked Crab Pasta is a lifesaver for busy home cooks looking to simplify meal preparation! You can prepare the creamy mixture up to 24 hours in advance by cooking the pasta, sautéing the vegetables, and mixing in the crab meat and sour cream. Store the mixture in an airtight container in the refrigerator, but hold off on adding the cheese until you’re ready to bake; this ensures it melts perfectly without becoming overly greasy. When you’re set to serve, simply transfer the mixture to a greased baking dish, top with cheese, and bake as directed. You’ll enjoy the same delicious taste with minimal effort, making weeknight dinners a breeze!
