What is Crab Oscar?
Named after King Oscar II of Sweden based on his love of the ingredients in this dish, Chefs created the oscar to pair with veal. Since then, oscar topping has found itself perched on top of steaks, fish, chicken, and seafood like shrimp or lobster. Crab Oscar or Steak Oscar, usually contains crab, but you can easily substitute the crab with freshly cooked lobster. Both offer a delicate sweetness that makes this dish suitable for pairing with bolder flavors.
Typically, Steak Oscar is presented in layers, with the main protein (steak) on the bottom, topped with 4-6 cooked asparagus spears, the lump white crab, followed by the hollandaise orย bearnaise sauce on top. Our recipe takes all the guesswork out by combining the crab with a delicious creamy sauce right on your stovetop. If you are a visual learner, please refer to the video below on how to make this steak topping.
Ingredients for this recipe
- Lump white crabmeat: Fresh or canned
- Shallot
- Celery: Don’t like celery? Sub with cooked leeks or chopped green onions.
- Fresh lemon juice: One large lemon should do.
- Unsalted butter
- Mayonnaise: The real stuff, not the tangy zippy sandwich spread. Real mayonnaise offers a mellow-flavored creaminess to the steak oscar.
- Sour cream: Or, if you want to be fancy, reach for the creme fraiche.
- Garlic: Two medium-sized cloves of garlic, minced.
- Dijon mustard: I’ve found that this is the best mustard for this recipe. Yellow mustard contains too much vinegar, while Dijon is mellow and made with wine.
- Hot sauce: This is purely optional.
- Salt and black pepper
