Directions
Spice-Crusted Beef Tenderloin
Preheat oven to 400°F. Add squash to oven (recipe follows). Rub Beef & Lamb seasoning all over tenderloin and let sit at room temperature for 1 hour.
Heat a large oven-proof skillet over high heat until almost smoking. Add olive oil and brown meat 1-2 minutes per side. Place skillet in the oven until a meat thermometer registers 115-125°F, about 16 minutes. Remove from oven and let stand at least 10 minutes before slicing.
Serve with mustard aioli and caramelized acorn squash (recipes follow).
Caramelized Acorn Squash
Preheat oven to 400°F. Combine butter, brown sugar and salt in a large bowl.
Toss in squash wedges to coat completely.
Spread out on two baking sheets and roast, turning occasionally, until well caramelized, about 45 minutes.
Grainy Mustard Aioli
Combine Dijon, egg yolk, lemon juice, salt, and pepper. Slowly whisk in olive oil until thickened. Thin with water if necessary.
Whisk in horseradish, grainy mustard, and water.
