Ingredients: Corned Beef with Mustard Parsley Sauce

Here’s what you’ll need to bring this recipe to life:
- 1.5kg corned beef – This is the star of the show. Look for high-quality, well-marbled beef to ensure tenderness.
- 1/4 cup apple cider vinegar – Adds a subtle tang that balances the sweetness of the brown sugar.
- 2 tablespoons brown sugar – Caramelizes slightly during cooking, enhancing the beef’s richness.
- 1 medium brown onion, roughly chopped – Provides sweetness and depth to the meat’s flavor.
- 4 cloves – A classic seasoning for corned beef, adding warmth.
- 1/2 teaspoon whole black peppercorns – For a bold, earthy note.
- 2 dried bay leaves – Infuse the meat with a subtle herbal aroma.
- 500g chat potatoes – A boiled or roasted side that absorbs the sauce beautifully.
- 1 bunch Dutch (baby) carrots, trimmed, peeled, and steamed – Adds color and sweetness.
- Steamed green beans – A light, fibrous contrast to the rich beef.
- Mustard Parsley Sauce Ingredients:

– 2 cups milk – Adds richness and smoothness.
– 2 teaspoons wholegrain mustard – Delivers a pungent, flavorful kick.

Step-by-Step Instructions
Step 1: Prepare the Corned Beef Marinade
In a large pot or slow cooker, combine the corned beef, apple cider vinegar, brown sugar, chopped onion, black peppercorns, and bay leaves. Stir well to ensure the beef is evenly coated. Bring to a simmer, then reduce heat to low. Cover and cook for 6–8 hours (or until the meat is fork-tender). This slow cooking process breaks down the connective tissues, making the beef incredibly tender.
Pro Tip: If you’re short on time, you can use an Instant Pot. Cook on high pressure for 75 minutes, then naturally release the pressure.
Step 2: Make the Mustard Parsley Sauce
While the beef cooks, prepare the sauce. In a saucepan, melt the butter over medium heat. Add the flour and whisk constantly for 1–2 minutes to create a roux. Gradually pour in the milk, stirring constantly to avoid lumps. Cook until the sauce thickens (about 5 minutes). Remove from heat and stir in the wholegrain mustard and chopped parsley. Taste and adjust seasoning if needed.
Chef’s Hack: For a smoother sauce, pass it through a sieve or blend it briefly in a blender.
Step 3: Slice and Serve
Once the beef is done, slice it against the grain for maximum tenderness. Serve it alongside steamed green beans, chopped carrots, and chat potatoes. Drizzle the mustard parsley sauce over the beef or offer it on the side for dipping.
Substitution Idea: If you don’t have mustard, substitute with 2 tablespoons of sour cream or mayonnaise for a creamier sauce.

People Also Ask: Corned Beef with Mustard Parsley Sauce

How do you make a mustard sauce for corned beef?
The key to a great mustard sauce for corned beef lies in balancing its ingredients. Start with a roux of butter and flour to create a creamy base. Then, mix in milk for richness and wholegrain mustard for pungency. Fresh parsley adds brightness, while a touch of brown sugar or honey can mellow the mustard’s sharpness. The result is a sauce that’s neither overpowering nor bland. For best results, let the sauce simmer gently after adding the mustard to help the flavors meld. This method ensures a smooth, cohesive texture that complements the beef’s tenderness.
What is parsley sauce made of?
A parsley sauce recipe typically combines fresh parsley with a creamy base like butter, milk, or cream. In this recipe, we use butter and milk to create a smooth texture, then add chopped parsley for flavor. The sauce can be adjusted by varying the herb amount or adding spices like garlic or lemon zest. It’s a versatile component that can be used for meats, vegetables, or even as a dipping sauce.
Pro Tip: If using dried parsley, reduce the quantity by half to avoid bitterness.
What do you serve with corned beef?
Corned beef pairs well with a variety of sides. Traditional options include potatoes, carrots, and greens like green beans or cabbage. For this recipe, chat potatoes, steamed carrots, and green beans are excellent choices. The mustard parsley sauce acts as both a dip and a seasoning, elevating even simple sides. For a heartier meal, serve with rice or crusty bread to soak up the sauce.
Alternative Idea: A warm baguette with the sauce drizzled on top makes a fantastic appetizer or snack.
How do you make corned beef tender?
Achieving tender corned beef requires low-and-slow cooking. Whether you braise it in a pot or use a slow cooker, the key is to cook it until it’s fork-tender. If you’re short on time, an Instant Pot can reduce cooking time to about 90 minutes. Another tip is to slice the beef against the grain, which shortens muscle fibers and ensures each bite is juicy. If the beef seems too tough, simmer it in the sauce for an extra 20–30 minutes to break down residual collagen.
