The Brisket Base
You have options here:
🔥 Option 1: Smoked or Oven-Baked Brisket
If you’re making brisket from scratch, go for it! Whether you use a smoker, Dutch oven, or slow cooker, cook it low and slow until fall-apart tender. Here’s a quick dry rub you can use:
| Spice Rub Mix | Amount |
|---|---|
| Brown sugar | 2 tbsp |
| Smoked paprika | 1 tbsp |
| Garlic powder | 1 tsp |
| Onion powder | 1 tsp |
| Black pepper | 1 tsp |
| Kosher salt | 1 tbsp |
| Cayenne (optional) | ½ tsp |
Rub brisket generously, cook at 275°F (covered) for 5–6 hours, or until it pulls apart easily.
🥩 Option 2: Leftover Brisket
This recipe works beautifully with leftover brisket — just reheat with a bit of broth or BBQ sauce to keep it moist.
The Pickled Onion Topping
Pickled onions are fast, easy, and addictive. Here’s how to make them:
