Method
Preparation
1
Pat the beef steaks dry with paper towels and season generously with salt and black pepper on both sides. Let them rest at room temperature for 15 minutes.
Searing
2
In a large cast-iron skillet or Dutch oven, melt 2 tablespoons of butter over medium-high heat until it begins to foam.
3
Sear the seasoned beef steaks for 3-4 minutes per side until a deep golden-brown crust forms. Remove the steaks and set aside.
Building the Braising Base
5
Add the sliced yellow onions and cook, stirring occasionally, for 30-40 minutes over medium-low heat until deeply caramelized and golden-brown, reducing heat if they start to burn.
6
Add the minced garlic and cook for 1 minute until fragrant.
Braising
7
Pour in the chicken broth and stir to release any browned bits from the bottom of the pan.
8
Whisk in the whole-grain mustard and red wine vinegar until combined.
9
Return the seared beef steaks to the pan, nestling them into the onion mixture. The liquid should come halfway up the sides of the steaks.
Finishing and Serving
11
Remove the lid and increase heat to medium. Simmer for 5-7 minutes to slightly reduce and concentrate the sauce.
12
Taste the braising liquid and adjust seasoning with salt and black pepper as needed.
13
Transfer the steaks to a serving platter, spoon the caramelized onions and rich sauce over the top, and garnish generously with freshly chopped parsley.

Safety & Storage
Cooking Temperature
Sear steaks at medium-high heat until golden-brown crust forms, then braise at low heat (covered) for 45-50 minutes until fork-tender. Final sauce reduction requires medium heat for 5-7 minutes.
Chicken broth must reach internal temperature of 165°F (74°C) during the braising phase to eliminate pathogens. Use a meat thermometer to verify the liquid near the beef reaches safe temperature before serving.
Handling
Pat beef steaks dry and season at room temperature for 15 minutes before cooking. Use tongs to handle hot steaks and turn halfway through braising.
Cross Contamination
Use separate cutting boards and utensils for raw beef versus vegetables. Wash hands thoroughly after handling raw meat before touching other ingredients.
Storage
Refrigerate leftovers within 2 hours in airtight containers. Consume within 3-4 days or freeze for up to 3 months. Reheat to 165°F throughout before serving.
High Risk Population
Ensure chicken broth is fully heated during braising. Vulnerable populations should verify all ingredient labels for hidden allergens and sulfites.
Allergen Warning
Four allergen groups present: dairy (butter), mustard, sulfites, and potential gluten. For severe allergies, use verified gluten-free chicken broth and check mustard label for cross-contamination risks.
Equipment Safety
Use oven mitts when handling cast-iron skillet or Dutch oven as it retains significant heat. Cover with tight-fitting lid during braising to prevent burns from escaping steam.
Pro Tips
Technique
When you sear the steaks, the pan must be hot enough that you hear it sing. One flip, good crust, then we build the rest.
Substitution
If you don't have whole-grain mustard, a good Dijon works fine—just add a few mustard seeds if you want that texture.
From the chef
This braise is built on two things that take their time: a good sear and slow-cooked onions. You brown the steak until there is real color on it, then you pull it and let the onions go until they are soft and golden and sweet. Whole-grain mustard goes in with the broth, a splash of red wine vinegar sharpens the sauce, and then the beef goes back in and you leave it alone for nearly an hour. By the time you lift the lid, the meat yields to a fork and the sauce has thickened around the onions into something rich and proper. Parsley over the top, bread on the side.
