Herb-Crusted Roast Beef with Tangy Mustard Rub

I love this roast for several reasons:

• Flavorful and tender: the herb-mustard crust adds bold flavor while keeping the meat juicy.
• Simple to prepare: straightforward searing and roasting steps.
• Crowd-pleaser: ideal for family meals, dinner parties, or holidays.
• Cost-effective: a tasty alternative to pricier prime rib or tenderloin.

What You’ll Need

Gather the following ingredients for Herb Mustard Crusted Roast Beef:

• Beef roast: 2–3 lb top sirloin or eye of round work well.
• Avocado oil: for searing; it has a high smoke point.
• Salt and freshly ground pepper: to season the roast.
• Fresh herbs and garlic: finely chopped parsley, oregano, thyme, rosemary and minced garlic for the crust.
• Hot mustard: Dijon or a German-style hot mustard mixed with the herbs makes the crust.
• Creamy Herb Sauce (optional): a chilled or warm herb sauce complements the roast beautifully.

Detailed ingredient amounts and full directions are in the recipe card below.

Equipment Needed

You’ll want:

• Cast iron pan: a 12-inch skillet is ideal for searing and transferring to the oven.
• Digital meat thermometer: the most reliable way to hit your preferred doneness.

How To Make Herb Mustard Crusted Roast Beef

Quick overview of the method:

1. Sear the roast: Pat the meat dry and season with salt and pepper. Heat avocado oil in a cast iron pan over medium-high heat and sear the roast on all sides until golden-brown. Transfer the skillet to a preheated 350°F (180°C) oven and roast for 20 minutes.
2. Prepare herb-mustard mixture: Combine the chopped parsley, oregano, thyme, rosemary, minced garlic, and mustard in a small bowl.
3. Apply the crust: Remove the pan from the oven and spread the herb-mustard mixture over the top and sides of the roast.
4. Finish roasting: Return the roast to the oven and cook to your desired doneness. For medium-rare, remove when the internal temperature reads about 125°F; for medium, remove at about 135°F. These targets are intentionally 5°F below final doneness to allow for carryover cooking while resting.
5. Rest and slice: Transfer the roast to a cutting board, tent loosely with foil, and rest for 10 minutes before slicing. Serve with your preferred sauce and enjoy.

What To Serve With Roast Beef

Classic pairings enhance this dish. Try:

• Sauces: Creamy Herb Sauce is an excellent match, or try a Gorgonzola cream sauce, mushroom cream sauce, or Dijon cream sauce.
• Potatoes: mashed, cheesy, roasted, or baked.
• Vegetables: roasted asparagus, Brussels sprouts, mixed root vegetables, garlic butter green beans, or steamed broccoli.
• Salads: a crisp green salad or a composed seasonal salad pairs well.
• Stuffing: savory bread-based stuffing makes a hearty side.
• Crusty bread: fresh bread and butter are always welcome.

Helpful Tips

Bring roast to room temperature

Remove the roast from the refrigerator 45–60 minutes before cooking so it cooks more evenly.

Cooking time and temperature

Cooking time depends on roast size and desired doneness. Use a digital meat thermometer for accuracy. For medium-rare, remove the roast at about 125°F; for medium, remove at about 135°F. Temperatures are suggested 5°F below final target to allow for carryover while resting.

Rest before slicing

Tent the roast loosely with foil and let it rest for 10 minutes. Resting lets the juices redistribute, producing a juicier slice.

Choose quality meat when possible

When you can, choose high-quality, responsibly raised beef. Local farms and reputable butchers often offer well-sourced options. Prioritizing better quality meat can improve the flavor and texture of the finished roast.
