Why it works: Beef and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Fillets of Beef
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the rolls
Cut the steak into strips about 3 inches wide.
Beat the strips with a chopper until flat and tender.
Mix the chopped mushrooms with salt, pepper, and butter. Lay the mushroom mixture over the steak strips.
Roll the strips up around the mushroom mixture.
Secure the rolls with a coarse needle and thread or tiny skewers.
Bake and finish the gravy
Place the fillets in a pie dish. Cover the dish with another dish to retain steam.
Bake the fillets in a preheated oven at 350°F (175°C). Turn the fillets occasionally.
Thicken the gravy in the baking dish with flour and butter. Add mushroom ketchup to the gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Forms the main body of the fillets and cooks into tender meat when beaten and baked.
- Fresh mushrooms
- Adds moisture and savory, earthy flavor inside the rolls and to the gravy.
- Butter
- Adds richness and moisture, melting into the mushrooms and gravy during baking.
- Flour
- Thickens the pan juices into a smooth gravy as they cook down.
- Mushroom ketchup
- Adds concentrated savory depth to the gravy.
The step that matters
Covering the dish to retain steam. Covering the baking dish traps moisture so the beef stays juicy and the juices can form the gravy. Without a cover, the surface can dry out before the beef is cooked through.
