• Ready to create an unforgettable meal? Here are the ingredients!
For the Pasta Base
- 16 oz pasta – Use Barilla Penne for best results; any pasta shape can work.
For the Crab Filling
- 16 oz crab meat – Lump crab is preferred for better texture; claw meat or well-drained canned crab works as budget-friendly alternatives.
- 14 oz sour cream – Daisy brand is recommended for creaminess; Greek yogurt can be a lighter substitute.
- 1 bell pepper – Any bell pepper color works; can be omitted for a simpler dish.
- 1 onion – Yellow onion is ideal; shallots can be used for a milder taste.
For the Flavor
- 4 tbsp butter – Kerrygold unsalted butter is preferred; olive oil is a healthy substitute.

- 1/2 tsp salt – Adjust based on dietary needs.
- 1/2 tsp pepper – Use freshly ground for better flavor.
- 1/4 tsp smoked paprika – Regular paprika can be used for a subtler taste.
For the Topping
- 4 oz Swiss cheese – Freshly grated is ideal; Gruyere is a delicious variation.

Step‑by‑Step Instructions for Baked Crab Pasta
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) to ensure it’s ready when your baked crab pasta is assembled. This temperature allows for even cooking and a beautifully melted cheese topping. While the oven warms up, you can focus on preparing the pasta and other ingredients.
Step 2: Cook the Pasta
In a large pot, bring salted water to a rolling boil and add 16 oz of pasta. Cook until just al dente, which is typically 2 minutes less than the package instructions. Draining the pasta early prevents it from becoming mushy during baking. Set the drained pasta aside, allowing it to cool slightly as you prepare the other components.
Step 3: Sauté the Vegetables
In a large skillet, melt 4 tablespoons of butter over medium heat. Once the butter has melted, add the diced onion and bell pepper, cooking for about 5-7 minutes, or until they are tender and fragrant. You’re looking for the onions to turn translucent and the bell pepper to become softer, adding a lovely sweetness to your baked crab pasta.
Step 4: Add the Seasonings
Once your vegetables are sautéed, mix in the dried oregano, garlic powder, salt, pepper, and smoked paprika. Stir the seasonings for about 30 seconds, allowing the aromas to bloom and fill your kitchen. This step enhances the overall flavor profile of the dish, making your baked crab pasta especially delightful.
Step 5: Combine Ingredients in a Bowl
In a large mixing bowl, gently combine the cooked pasta, sautéed vegetables, 16 oz of lump crab meat, and 14 oz of sour cream. Use a spatula to mix everything together carefully to avoid breaking apart the crab pieces. Ensuring an even distribution of the creamy mixture is key to achieving a rich texture throughout your baked crab pasta.
Step 6: Transfer to Baking Dish
Grease a 9×13 inch baking dish, then pour the pasta mixture into it, spreading it evenly. This helps create a cohesive bake, and the greased dish prevents sticking. Top the pasta mixture generously with 4 oz of grated Swiss cheese and 4 oz of cheddar cheese, ensuring every bite is cheesy and delicious.
Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake for about 20 minutes. Keep an eye on the dish; it’s ready when the cheese is melted, bubbly, and golden brown on top. This step transforms your ingredients into a warm, comforting baked crab pasta that will have everyone eager to dig in.
Step 8: Rest and Garnish
After removing your baked crab pasta from the oven, let it rest for 5-10 minutes to cool slightly. This resting time allows the flavors to meld and makes serving easier. Before plating, sprinkle chopped green onions on top for a fresh garnish, adding a pop of color and a mild onion flavor that complements the rich dish.

Make Ahead Options
Preparing your baked crab pasta in advance is a great way to save time during busy weekdays! You can assemble the entire casserole up to 24 hours ahead. Just prepare the pasta, sauté the vegetables, and mix everything together in your baking dish. Cover it tightly with plastic wrap and refrigerate to maintain freshness. For the best quality, set it out at room temperature for about 30 minutes before baking. When you’re ready to serve, simply pop it in the preheated oven and bake as directed. You’ll enjoy a delicious, hearty meal with minimal effort, allowing you to relax and unwind after a long day!
