No pastry makes this beef wellington Keto and delicious.


For the Duxelles:

  • 3 large button mushrooms
  • 1 Tablespoon (10 g) onions, chopped
  • 1 teaspoon (3 g) garlic powder
  • 1/2 teaspoon (3 g) salt
  • 2 Tablespoons (30 ml) olive oil

Other Ingredients:

  • 1 9-ounce (252 g) filet mignon
  • 8 thin slices of prosciutto (or 4 ham slices)
  • 1 Tablespoon (14 g) yellow mustard
  • 1/2 Tablespoon (7 g) salt
  • 2 Tablespoons (30 ml) olive oil to cook in


  1. Preheat oven to 400 F (200 C).
  2. Make the duxelles by blending the mushrooms, onions, garlic, salt, and olive oil together until pureed.
  3. Then heat the mixture in a pan for 10 minutes on medium heat.
  4. Place a large piece of cling-film onto the counter and place the slices of prosciutto side-by-side (overlapping slightly) to form a rectangular layer.
  5. Spread the duxelles over the prosciutto layer.
  6. Sprinkle the 1/2 Tablespoon of salt over the filet mignon.
  7. Pan-sear the filet mignon in 2 Tablespoons of olive oil.
  8. Spread the 1 Tablespoon of mustard on the seared filet mignon and place in the middle of the prosciutto and duxelles layer.
  9. Use the cling-film to wrap the prosciutto around the filet mignon. Then wrap the cling-film around the package to secure it. Use a second piece of cling-film to pull the prosciutto-wrapped package tighter together. Place in fridge for 15 minutes.
  10. Remove the cling-film from the refrigerated prosciutto-wrapped beef and place on a greased baking tray.
  11. Bake for 20-25 minutes (it should be pink when you cut into it).
  12. To serve, carefully cut the Beef Wellington in half.
