A scoop of creamy crab Oscar on top of a sizzling steak takes surf and turf to a whole new level. It's a dish that is sure to impress and is suitable for an anniversary dinner, Valentine's Day, or other occasions. This steak topper is not only easy to prepare but is incredibly flavorful and will take surf and turf to a new level.

The traditional "Oscar" topping is named in honor of King Oscar II who reigned in Sweden from 1872 until 1907. He is the great-grandfather of the current king of Norway, Harald V. You may know his visage from sardine cans. He was fond of veal cutlets topped with crabmeat or lobster in Hollandaise sauce or Béarnaise sauce, garnished with asparagus spears. Today, you can find steak and fish topped in this fashion.

This recipe makes it easy as you will be using mayonnaise and sour cream rather than producing a fancy sauce. The result is just as delicious with much less work. That leaves time to lavish your attention on your guests.


  • 1 tablespoon olive oil

  • 2 tablespoons butter

  • 1 small onion, finely chopped

  • 1/4 cup finely chopped celery (or use less or omit if preferred)

  • 2 cloves garlic, minced

  • 1 pound crabmeat

  • 1 large lemon, juiced

  • 1/2 teaspoon hot sauce (or use less or omit if preferred)

  • 1/4 teaspoon salt

  • 1/4 teaspoon ground black pepper

  • 2 tablespoons mayonnaise

  • 2 tablespoons sour cream

  • Any unused mixture should be stored in an airtight container in the refrigerator. You can reheat it before using. Plan to use it within two to three days after preparation.
  • This crab Oscar topper can also be used on seafood, especially firm fish such as salmon or swordfish. You can swap the crab for crawfish or lumps of lobster and still be true to the Oscar tradition.
  • The asparagus is typically steamed, which you can do in the microwave. This retains the bright green contrast. However, your asparagus will be tastier if you roast it in the oven or on the grill.
