Step-by-Step Instructions
1. Prep & Sear the Roast
- Season the chuck roast with salt and sear on both sides in hot oil until browned.
- Slice one onion and place it in the slow cooker along with rosemary, thyme, beef broth, red wine, Worcestershire sauce, and soy sauce.
- Add the seared roast, then season with beef bouillon powder and garlic powder.
2. Slow Cook the Beef
- Cover and cook the roast in the slow cooker on low for 6–8 hours or until fork-tender and juicy.
3. Caramelize the Onions
- While the beef cooks, slice the remaining onions.
- Melt cubed butter in a pan, add onions, season with salt and pepper, and cook on low until soft, sweet, and caramelized.
4. Make the Horseradish Sauce
- Mix mayo, horseradish, lemon juice, garlic powder, and pepper in a bowl.
- Chill in the fridge until ready to serve.
5. Shred the Beef & Strain the Au Jus
- Once cooked, remove the beef from the slow cooker and shred it with forks.
- Mix in the caramelized onions.
- Strain the leftover liquid from the slow cooker to use as dipping broth (au jus).
6. Assemble the Sandwich
- Slice the baguette, spread horseradish sauce on the bread, layer with the shredded beef-onion mix, and top with provolone.
- Wrap the sandwich in foil and heat in the oven until the cheese melts.
7. Make the Truffle Fries
- Slice potatoes into fries and soak in ice water.
- Fry until golden, then toss with white truffle oil, truffle salt, and fresh parsley.
- Serve hot with your sandwich and au jus on the side.
Pro Tips & Suggestions
- Low and slow wins—don’t rush the beef; let the flavors develop.
- Use a mandolin for evenly sliced onions and fries.
- No truffle oil? Use garlic oil and sea salt for a budget-friendly upgrade.
- Don’t skip the sauce—the horseradish adds the perfect creamy bite.
