Ingredients

For the Steak

  • 2 thick-cut ribeye or sirloin steaks
  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • 3 garlic cloves, lightly crushed
  • 2 sprigs fresh rosemary or thyme
  • 1 teaspoon salt
  • 1 teaspoon freshly ground black pepper

For the Creamy Mustard Sauce

  • 2 tablespoons butter
  • 2 cloves garlic, minced
  • 1 small shallot, finely chopped
  • 1 cup heavy cream
  • 2 tablespoons Dijon mustard
  • 1 tablespoon whole grain mustard
  • ½ cup beef broth
  • ½ teaspoon black pepper
  • Salt to taste
  • Fresh parsley or chives for garnish

Step-by-Step Instructions

Step 1: Prepare the Steak

Remove the steaks from the refrigerator about 30 minutes before cooking. Allowing the meat to come closer to room temperature helps it cook more evenly.

Pat the steaks dry using paper towels. This step is important because removing moisture allows the surface to develop a beautiful golden-brown crust.

Season both sides generously with salt and freshly ground black pepper.

Step 2: Sear the Steak

Heat a heavy skillet or cast-iron pan over medium-high heat until hot.

Add olive oil, then place the steaks into the pan. Let them cook without moving them for several minutes until a deep brown crust forms.

Flip the steaks and add butter, crushed garlic, and fresh rosemary or thyme to the pan.

Tilt the pan slightly and spoon the melted herb butter over the steaks repeatedly. This process adds incredible flavor and helps keep the steak moist.

Cook until the steak reaches your preferred doneness:

  • Rare: 125°F (52°C)
  • Medium rare: 135°F (57°C)
  • Medium: 145°F (63°C)

Remove the steaks from the pan and let them rest for 5–10 minutes.

Step 3: Make the Creamy Mustard Sauce

Using the same skillet, reduce the heat to medium.

Add butter and sauté the chopped shallots until softened. Add minced garlic and cook for about 30 seconds until fragrant.

Pour in the beef broth and scrape the bottom of the pan with a wooden spoon. These browned bits add deep flavor to the sauce.

Add heavy cream, Dijon mustard, and whole grain mustard. Stir well and allow the sauce to gently simmer until it thickens slightly.

Season with salt and pepper according to taste.

Step 4: Combine and Serve

Return the rested steaks to the pan briefly, or spoon the creamy mustard sauce generously over the top.

Finish with freshly chopped parsley or chives for color and freshness.

Serve immediately while the steak is warm and the sauce is creamy.

Cooking Tips for the Perfect Steak

Choose the Right Cut

Ribeye is excellent for this recipe because its marbling creates a juicy and flavorful result. Sirloin or strip steak are also great options.

Don’t Skip Resting the Steak

Resting allows the juices to redistribute throughout the meat, creating a tender and flavorful bite.

Use High Heat for the Crust

A hot pan creates the delicious browned exterior known as the Maillard reaction, which gives steak its deep savory flavor.

Avoid Overcrowding the Pan

If cooking multiple steaks, leave enough space between them so they sear instead of steaming.

Taste Your Sauce Before Serving

Mustard brands vary in strength, so adjust the cream, mustard, and seasoning balance to your preference.

Serving Suggestions

This creamy mustard steak pairs beautifully with classic sides:

  • Garlic mashed potatoes
  • Crispy roasted potatoes
  • Steamed asparagus
  • Sautéed green beans
  • Fresh garden salad
  • Buttered vegetables
  • Warm crusty bread

For a complete steakhouse-style dinner, serve it with roasted vegetables and a glass of your favorite drink.

Storage and Reheating

If you have leftovers, store the steak and sauce separately in airtight containers.

Refrigerate for up to 3 days.

To reheat, warm gently in a skillet over low heat with a little extra cream or broth to prevent the sauce from becoming too thick.

Avoid reheating the steak at high temperatures, as it may become tough.

Recipe Variations

Garlic Mushroom Mustard Steak

Add sliced mushrooms while preparing the sauce for an earthy, rich variation.

Spicy Mustard Steak

Add crushed red pepper flakes or a little cayenne pepper for extra heat.

Herb Butter Steak

Skip the cream sauce and finish the steak with garlic herb butter for a simpler version.

Chicken Version

This sauce also works beautifully with chicken breasts or chicken thighs.

Frequently Asked Questions

Can I use another type of mustard?

Yes. Dijon mustard provides a smooth tangy flavor, while whole grain mustard adds texture. You can adjust the combination based on your preference.

Can I grill the steak instead?

Absolutely. Grill the steak until it reaches your preferred doneness, then prepare the sauce separately on the stovetop.

How do I know when my steak is done?

The best method is using a meat thermometer. It gives the most accurate result without cutting into the steak.

Can I make the sauce ahead of time?

Yes. Prepare the sauce and refrigerate it for up to two days. Reheat gently before serving.
