I still remember the first time I decided to make chili with leftover prime rib. It was after a particularly festive holiday dinner, and we had a glorious, albeit slightly diminished, roast sitting in the fridge. The thought of just reheating slices, while perfectly acceptable, felt a bit uninspired. Then it hit me: chili! My family, initially a little skeptical about using such a luxurious cut of beef in a rustic dish, were absolutely blown away. The richness of the prime rib melted into the spicy, smoky tomato base, creating a depth of flavor that no ground beef chili could ever replicate. The tender, succulent pieces of beef were little treasures in every spoonful. It wasn’t just chili; it was an event. Now, Slow Cooker Prime Rib Chili has become our celebratory “day-after” tradition, a dish that’s both comforting and incredibly indulgent. The slow cooker does all the heavy lifting, making it surprisingly easy to achieve this bowl of pure, beefy bliss.

Instructions

Follow these steps for a perfectly rich and flavorful Slow Cooker Prime Rib Chili:

Prepare the Prime Rib: If your prime rib isn’t already cooked, this recipe assumes you’re using leftovers. Trim any large, hard pieces of fat from your cooked prime rib. Cut the meat into generous 1-inch cubes. Set aside.
Sauté Aromatics (Flavor Building): Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the chopped onion and bell peppers. Sauté for 5-7 minutes, or until they begin to soften and the onion becomes translucent.
Add Garlic and Jalapeño: Stir in the minced garlic and jalapeño (if using). Cook for another 1-2 minutes until fragrant. Be careful not to burn the garlic.
Brown the Prime Rib (Optional but Recommended): Even though the prime rib is cooked, a quick sear can enhance its flavor. Add the cubed prime rib to the skillet with the vegetables. Cook for 2-3 minutes per side, just until lightly browned. This step adds another layer of Maillard reaction goodness. If your skillet is crowded, do this in batches. If your prime rib already has a very good sear from its initial cooking, you can skip this and add it directly to the slow cooker later.
Deglaze (If Using Wine): If using red wine, pour it into the hot skillet. Scrape up any browned bits from the bottom of the pan with a wooden spoon – these are packed with flavor! Let the wine simmer for 1-2 minutes, allowing the alcohol to cook off slightly.
Transfer to Slow Cooker: Transfer the sautéed vegetables, browned prime rib (and any pan juices, including the deglazing liquid if used) to the basin of your slow cooker (6-quart or larger recommended).
Add Remaining Chili Base Ingredients: To the slow cooker, add the crushed tomatoes, diced tomatoes (undrained), tomato paste, beef broth, rinsed and drained kidney beans, and rinsed and drained black beans.
Stir in Spices: Add the chili powder, ground cumin, smoked paprika, dried oregano, cayenne pepper (if using), bay leaves, kosher salt, black pepper, cocoa powder (if using), and brown sugar (if using). Stir everything together thoroughly to ensure the spices are well distributed.
Slow Cook: Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours. The longer, slower cook time on low allows the flavors to meld beautifully and the prime rib to become even more tender.
Taste and Adjust Seasoning: About 30 minutes before the end of the cooking time, remove the bay leaves. Taste the chili and adjust seasonings as needed. You might want more salt, chili powder, or a pinch more cayenne for heat.
Thicken (Optional): If you prefer a thicker chili, prepare the masa harina slurry by whisking the masa harina with warm water until smooth. Stir the slurry into the chili during the last 30 minutes of cooking. Cook, uncovered, on HIGH for this final period to allow it to thicken. Alternatively, you can remove the lid for the last 30-60 minutes of cooking on LOW to allow some liquid to evaporate.
Rest Before Serving: Once cooked, turn off the slow cooker and let the chili rest for at least 15-20 minutes before serving. This allows the flavors to settle and deepen even further.
Serve Hot: Ladle the hot chili into bowls and serve with your favorite toppings.

Additional Tips

Don’t Skip Searing (Even for Cooked Meat): While the prime rib is already cooked, taking a few extra minutes to sear the cubes in a hot pan before adding them to the slow cooker develops a deeper, richer, beefier flavor due to the Maillard reaction. It also adds a pleasant texture.
Bloom Your Spices: For an even more intense flavor from your dried spices (chili powder, cumin, paprika), you can “bloom” them. After sautéing the aromatics and browning the meat, add the spices directly to the skillet with a little oil from the pan. Stir constantly for about 30-60 seconds until fragrant before adding liquids. This awakens their essential oils.
Layer Flavors with Umami Boosters: Besides the optional cocoa powder and brown sugar, consider adding a tablespoon of Worcestershire sauce or a teaspoon of soy sauce (or tamari for gluten-free) along with the beef broth. These ingredients add a savory depth (umami) that complements the beef and tomatoes beautifully.
Control the Heat Wisely: If you love spicy chili, don’t just rely on cayenne. Include the seeds from your jalapeños, add a minced chipotle pepper in adobo sauce (for smoky heat), or use a spicier variety of chili powder. If you prefer mild chili, omit the jalapeño seeds and cayenne, and choose a mild chili powder. You can always add hot sauce at the table.
Let it Rest and Meld: Chili, like many stews, tastes even better the next day after the flavors have had more time to meld and marry. If you can, make it a day ahead, or at least let it rest for a good 30 minutes to an hour after cooking before serving. This also allows it to thicken slightly as it cools.

FAQ Section

Q1: Can I use a different cut of beef if I don’t have leftover prime rib?
A1: Absolutely! While prime rib makes it exceptionally luxurious, you can substitute with other cuts. For a slow cooker chili, good options include:
* Chuck Roast: Cut into 1-inch cubes. It will become very tender during the long cook time. You’ll definitely want to sear this raw beef before adding it to the slow cooker.
* Beef Stew Meat: Already cubed, convenient. Sear it as well.
* Brisket: Another cut that benefits from low and slow cooking, resulting in tender, flavorful meat.
Adjust cooking time if starting with raw beef; it might need the full 8 hours on low to become perfectly tender.

Q2: Can I make this prime rib chili spicier or milder?
A2: Yes, easily!
* For Spicier Chili:
* Add more jalapeños, and include their seeds and membranes.
* Incorporate 1-2 minced chipotle peppers in adobo sauce (this also adds a smoky flavor).
* Increase the amount of cayenne pepper.
* Use a “hot” variety of chili powder.
* Add a few dashes of your favorite hot sauce during or after cooking.
* For Milder Chili:
* Omit the jalapeño peppers entirely, or use only a small amount with seeds and membranes removed.
* Skip the cayenne pepper.
* Ensure you’re using a mild chili powder.
* Bell peppers add flavor without heat.

Q3: Can I prepare this recipe on the stovetop instead of a slow cooker?
A3: Yes, you can adapt this recipe for the stovetop. Follow steps 1-5 in a large, heavy-bottomed Dutch oven or stockpot. Then, instead of transferring to a slow cooker, add the remaining chili base ingredients and spices (steps 6-8) directly to the pot. Bring the chili to a simmer, then reduce the heat to low, cover, and let it cook for at least 1.5 – 2 hours, or until the flavors have melded and the (already cooked) prime rib is heated through and tender. Stir occasionally to prevent sticking. If using raw beef cubes like chuck, you’ll need to simmer for 2-3 hours or until the beef is very tender.

Q4: How long will leftover prime rib chili last, and how should I store it?
A4:
* Refrigerator: Allow the chili to cool completely, then transfer it to airtight containers. It will keep well in the refrigerator for 3-4 days. The flavors often improve by the second day!
* Freezer: For longer storage, cool the chili completely and then transfer it to freezer-safe containers or heavy-duty freezer bags. Leave about an inch of headspace for expansion. Frozen chili can last for 4-6 months. Thaw it overnight in the refrigerator before reheating gently on the stovetop or in the microwave.

Q5: What if I don’t have all the specific spices listed, like smoked paprika or cocoa powder?
A5: While each spice adds its unique nuance, the most critical spices for chili are chili powder and cumin.
* Smoked Paprika: If you don’t have it, you can use regular sweet paprika, though you’ll miss the smoky element. A tiny dash of liquid smoke (use very sparingly) could be an alternative if you have it.
* Cocoa Powder: This is an optional ingredient for depth and a subtle richness, often found in Texas-style chili. You can omit it without a major impact on the overall dish, though it does add a “secret ingredient” complexity.
* Oregano: If you only have Italian seasoning, it often contains oregano and can be used as a substitute in a pinch, though it will bring other flavors too.
The key is to build a good flavor base with onions, garlic, peppers, tomatoes, chili powder, and cumin. The other spices enhance it, but the chili will still be delicious without every single one.
