Recipe Tips and Tricks
Pat the roast dry—ensures a good sear; moisture prevents browning. Sear first—locks in juices and boosts flavor; it’s a must! Slice onions thick—keeps them from dissolving; ½-inch rings work best. Use fresh garlic—dried lacks punch; mince it fine for even flavor. Check doneness early—crock pots vary; aim for 135°F for medium-rare.

Dried thyme enhances depth—½ tsp (negligible macros) subtle and earthy.
Variations and Substitutions
Swap sirloin tip for chuck roast or rump roast—3 lbs (70g protein, 60g fat), fattier or tougher but tenderizes well. Use avocado oil or butter instead of olive oil—2 tbsp (28g fat), richer or creamier sear. Sub onions with shallots or leeks—2 medium (20g carbs), milder or earthier. Replace beef broth with red wine or chicken broth—1 cup (5g carbs or 2g protein), bolder or lighter. Add rosemary or oregano—½ tsp each (negligible macros), for different herby notes.
