Mustard roast beef with aioli

Mustard roast beef with aioli is a delicious and savory dish perfect for any family dinner or special occasion. The combination of tender roast beef with a tangy mustard crust, paired with a creamy aioli sauce, creates a balanced and flavorful experience. This recipe is straightforward and can be a great addition to your culinary repertoire.

Ingredients:

2 garlic cloves
6g
1 cup mayonnaise
230g
1/3 cup sour cream
72g
2 tbsp chives
30g
2 lb beef
910g
2 tbsp mustard
30g
1/3 cup tarragon (estragon)
50g

Instructions:

1. Combine Ingredients:
- In a medium-sized bowl, combine the minced garlic, 1 cup of mayonnaise, 1/3 cup of sour cream, and 2 tablespoons of finely chopped chives.
2. Mix Thoroughly:
- Stir the mixture until all the ingredients are well incorporated. Ensure the aioli is smooth and the garlic and chives are evenly distributed.
3. Refrigerate:
- Cover the bowl with plastic wrap and refrigerate the aioli for at least 30 minutes to allow the flavors to meld.
4. Season the Beef:
- Pat the 2 lb of beef dry with paper towels to ensure a good sear.
- Rub the beef with 2 tablespoons of mustard, ensuring it is evenly coated.
5. Add Tarragon:
- Sprinkle the finely chopped 1/3 cup of tarragon over the beef, pressing gently so it adheres to the mustard-coated beef.
6. Roast the Beef:
- Place the seasoned beef on a roasting rack in a roasting pan.
- Roast in the preheated oven for about 20 minutes per pound for medium-rare, or until the internal temperature reaches your desired level of doneness (e.g., 130°F (54°C) for medium-rare).
- Use a meat thermometer to check the temperature.
7. Rest the Beef:
- Remove the beef from the oven and let it rest on a cutting board for 10-15 minutes. This allows the juices to redistribute throughout the meat.
8. Slice and Serve:
- Slice the beef thinly against the grain and serve with a generous dollop of the prepared aioli on the side.

Tips:

- For best results, use a meat thermometer to ensure your beef is cooked to your desired level of doneness. Medium-rare is typically recommended for roast beef.

- Let the beef rest for at least 10-15 minutes after roasting before slicing. This helps retain the juices and keeps the meat tender.

- Finely chop the garlic and mix it well into the aioli to ensure even distribution of flavor.

- Feel free to adjust the amount of mustard and tarragon based on your taste preference. If you like a stronger mustard flavor, add an extra tablespoon.

- When making the aioli, whisk the ingredients together until smooth and creamy for the best texture.

Serve your mustard roast beef with aioli alongside your favorite sides, such as roasted vegetables or a fresh salad, to enjoy a hearty and satisfying meal. This dish is sure to impress your guests with its rich flavors and easy preparation. Bon appétit!
