📖 Instructions

1. First thing, take your beautiful chuck roast out of the fridge about 30 minutes before you plan to start cooking. This helps it come closer to room temperature for a better sear. While it's chilling, get all your veggies and spices ready. Dice the onion, mince the garlic, slice the jalapeño (remember to deseed for less heat, if you wish!). Measure out your spices; it saves a frantic scramble later.
2. Pat the beef roast dry with paper towels—this is crucial for a good crust. Sprinkle it generously all over with salt and freshly ground black pepper. Heat 1 tablespoon of olive oil in a large, heavy-bottomed skillet (cast iron works wonderfully here!) over medium-high heat. Once the oil shimmers, carefully place the beef in the skillet. Sear it for about 3-4 minutes per side, until a deep golden-brown crust forms. You're not cooking it through, just building flavor. Remove the seared beef and set it aside on a plate.
3. Reduce the heat to medium. Add the remaining 1 tablespoon of olive oil to the same skillet. Toss in the diced onion and cook, stirring occasionally, for 5-7 minutes until it softens and turns translucent. Then, add the minced garlic and sliced jalapeño. Sauté for another minute until fragrant – oh, that smell! Make sure not to burn the garlic; a gentle golden hue is what we're after.
4. Now, stir in the chili powder, cumin, oregano, and a pinch of cayenne (if you're feeling bold!). Cook these spices with the onions and garlic for about 30 seconds, stirring constantly. This "blooming" of the spices in the hot oil really brings out their deep flavors. Trust me on this little step, it makes a huge difference.
5. Pour in the beef broth, scraping up any delicious browned bits from the bottom of the skillet with a wooden spoon. Those bits are pure flavor! Stir in the diced tomatoes (undrained) and the tomato paste. Whisk everything together until the tomato paste is fully dissolved and the mixture is well combined. Bring it to a gentle simmer.
6. Carefully transfer the seared beef roast to your slow cooker. Pour the simmering chili mixture from the skillet over the beef, making sure it's mostly submerged.
7. Cover the slow cooker with its lid. Cook on low for 6-8 hours or on high for 3-4 hours, or until the beef is incredibly tender and easily shreds with a fork. You'll know it's ready when it practically falls apart when you touch it. My slow cooker sometimes runs a bit hot, so I usually check it around the 6-hour mark on low.
8. Once cooked, remove the beef roast from the slow cooker and place it on a cutting board. Using two forks, shred the beef into bite-sized pieces. It should be so tender that it practically shreds itself.
9. Return the shredded beef to the slow cooker and stir it into the chili sauce. Let it warm through for another 10-15 minutes on low, allowing the shredded beef to soak up all those amazing flavors. Taste and adjust seasonings if needed—maybe a little more salt, a grind of pepper, or a dash of hot sauce if you like it zingier.
10. Serve your Flavorful Slow Cooker Chili Beef Roast hot with your favorite toppings. Think a dollop of sour cream or Greek yogurt, a sprinkle of fresh chopped cilantro, shredded cheddar cheese, or even some crushed tortilla chips for a little crunch. A side of warm cornbread? Yes please!
