Ingredient Notes
- Imitation crab meat: This adds a subtle seafood flavor that pairs beautifully with the cheese. Look for a flaky version that feels fresh; avoid any that look slimy.
- Shell pasta: The shape holds onto that cheesy sauce and crab bits perfectly! Make sure to cook it al dente so it doesn’t get mushy in the oven.
- Sour cream: It gives the dish that creamy texture and a slight tang. You can opt for Greek yogurt if you’re looking for a lighter choice!
- Swiss cheese: I love the nutty flavor it brings. Grate it fresh for the best melting results; pre-shredded stuff can be a bit waxy.
- Mild cheddar: This cheese adds warmth and that classic cheesy taste. Freshly grated is best; it’ll melt nicer and not clump together like pre-packaged cheese.

Recipe Tips
- If the casserole seems dry, adding an extra half cup of sour cream can help achieve a creamier texture.
- For well-seasoned flavor, make sure to adjust the spices and salt according to your taste before baking.
- When cooking the pasta, aim for al dente, usually around 7-8 minutes, to prevent mushiness after baking.
- If using frozen ingredients, doubling the baking time, about 1 hour, ensures everything heats through properly.
- For cheese that melts beautifully, hand-grating about 2 cups of cheese is recommended rather than using pre-shredded varieties.

Cheesy Crab Pasta Casserole
This Cheesy Crab Pasta Casserole is a delightful blend of imitation crab meat, shell pasta, and a creamy cheese mixture baked to perfection.
Equipment
- 3.5+ quart baking dish
- Large pot
- Medium skillet
Ingredients
- 14 ounces imitation crab meat flaked
- 16 ounces shell pasta boiled and drained
- 12 ounces sour cream light or full-fat
- 1 bell pepper seeded and sliced thinly
- 1 Vidalia onion jumbo, sliced thinly
- 4 tablespoons unsalted butter
- ½ teaspoon oregano
- ½ teaspoon garlic powder
- ¼ teaspoon salt
- ¼ teaspoon freshly ground black pepper
- 4 ounces Swiss cheese freshly grated
- 4 ounces mild cheddar freshly grated
Instructions
- Start by slicing the bell pepper and Vidalia onion into thin strips. As you slice, the sweet aroma will fill the kitchen. This indicates you are on the right track. These veggies add flavor and texture to the dish. Take care to avoid tears from the onion.
- Melt the unsalted butter in a large skillet over medium heat, and add the sliced onions. Cook for about 5 minutes until translucent and slightly caramelized. You want them soft, not burnt, as this step adds depth to the casserole.
- Add the sliced bell peppers into the skillet, stirring them with the onions. Cook for another 3 to 4 minutes until the peppers are tender and vibrant. Ensure they do not cook too long to maintain a bit of crunch.
- In a bowl, combine the Swiss and cheddar cheese, reserving a bit for topping. Grating your own cheese is crucial for achieving a great melting texture.
- In a large mixing bowl, combine the cooked shell pasta, imitation crab meat, sautéed vegetables, sour cream, and seasonings. Stir gently until everything comes together in a creamy mixture. Avoid over-mixing to maintain the integrity of the pasta.
- Spread the cheesy crab pasta mixture evenly in the greased baking dish. Ensuring even layers helps everything cook uniformly and prevents dry spots.
- Sprinkle the reserved cheese on top of the casserole, creating a golden, cheesy crust. This layer will melt and create a delicious topping as it bakes.
- Bake the casserole in the oven until bubbling and golden on top, around 20 minutes. As it bakes, you will experience a delightful aroma. Let it cool for a few minutes before serving, as it will be very hot inside.
Notes

Expert Tips: Ensure to use enough sour cream for a creamy texture and adjust spices and salt according to your taste before baking. When cooking the pasta, aim for al dente, typically about 7-8 minutes. For frozen ingredients, double the baking time to about 1 hour.
Reheating Instructions: Reheat in an oven preheated to 350 degrees F for about 20 minutes or until heated through.
Serving Suggestions: Serve with a side salad for freshness or pair with garlic bread for a complete meal. You can also top with extra cheese and green onions before serving.
Recipe Variations: Add cooked shrimp for a seafood medley or incorporate different colored bell peppers for variety. Mixing in spinach or kale can provide additional greens.
Ingredient Notes: Choose hand-grated cheese for optimal melting, as pre-shredded varieties contain additives that hinder quality. If you prefer real crab meat, adjust the seasoning accordingly.
