Brown Sugar and Dijon Baked Corned Beef Brisket
Tender, flavorful corned beef with a sticky-sweet Dijon glaze—perfect for Sunday suppers, sandwiches, or a cozy dinner.
Ingredients
-
1 (3–4 lb) corned beef brisket (flat cut, with spice packet)
-
1/3 cup brown sugar (light or dark)
-
3 tbsp Dijon mustard
-
Spice packet included with brisket
Instructions
1. Prep the Oven & Brisket
-
Preheat oven to 350°F (175°C).
-
Line a large baking sheet with heavy-duty aluminum foil long enough to fully wrap the brisket.
-
Place the brisket flat-side down on the foil. Pat dry thoroughly with paper towels.
2. Season & Glaze
-
Sprinkle the spice packet evenly over the brisket, pressing lightly.
-
In a small bowl, mix brown sugar + Dijon mustard into a thick paste.
-
Spread the paste evenly over the top and sides of the brisket.
3. Wrap & Bake
-
Fold the long sides of the foil up and seal, then fold the short ends to create a fully sealed packet.
-
Place the foil-wrapped brisket on the baking sheet and bake:
-
3 lbs: ~2 hr 30 min
-
4 lbs: ~3 hr
-
-
Rest wrapped 15–20 minutes before slicing.
4. Slice & Serve
-
Slice against the grain for tender pieces.
-
Serve with mashed potatoes, roasted veggies, or in a Reuben sandwich.
Notes
-
Glaze melting: Some glaze mixes with cooking juices—this makes an incredible au jus.
-
Slow cooker option: Place glazed brisket + ½ cup water/broth in slow cooker. Cook LOW 8–9 hr or HIGH 5–6 hr.
-
Tough brisket: Simply wrap and bake 20–30 min longer until fork-tender.
-
Storing leftovers: Refrigerate in airtight container up to 4 days, or freeze up to 3 months (slice before freezing).
