Ingredients

For the Roast Beef:

• 3–4 lbs roast beef (chuck or brisket works best)
• 1 cup celery, chopped
• 1 medium onion, chopped
• 3 bay leaves
• 4 cloves garlic, minced
• 1 tablespoon olive oil
• 1 teaspoon dried thyme
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ cup beef broth

For the Mashed Cauliflower:

• 1 head cauliflower, cut into florets
• 2 tablespoons butter
• ¼ cup heavy cream
• ¼ cup grated parmesan cheese

Step-by-Step Instructions

1. Sear the Roast

Heat olive oil in a large skillet over medium-high heat. Sear the roast beef on all sides for 4–5 minutes each, until browned. This locks in flavor.

2. Transfer to Slow Cooker

Place the roast in your slow cooker. Add chopped celery, onion, bay leaves, and garlic. Season with thyme, salt, and black pepper. Pour beef broth over the top.

3. Slow Cook to Tenderness

Cover and cook on low for 8 hours. The beef will become tender enough to shred with a fork.

4. Make the Cauliflower Mash

While the beef finishes cooking:

• Steam cauliflower florets for 10–12 minutes until very tender.
• Transfer to a food processor or use an immersion blender.
• Add butter, heavy cream, and parmesan. Blend until smooth and creamy.

5. Serve It Up

Plate generous scoops of mashed cauliflower topped with tender roast beef. Spoon over some cooking liquid from the slow cooker for added richness.

Tips for Success

• Searing is essential for a flavor-packed crust.
• Use chuck or brisket for the juiciest, shreddable texture.
• Don’t overblend the cauliflower—it can become gummy if processed too long.

Flavor Variations

• Add a splash of red wine to the slow cooker for deeper flavor.
• Infuse your mash with roasted garlic for extra flair.
• Spice up the beef with smoked paprika or chili flakes if you like heat.

Storage & Leftover Tips

• Store leftover beef and cauliflower separately in airtight containers.
