Pat the roast dry.
2-4 Lb Chuck Roast
Season evenly, on all sides, with the Cajun seasoning, smoked paprika, black pepper, and a pinch of salt. Note: if you end up with extra seasoning after rubbing the roast, save it for later. 3 Tbsp Cajun Seasoning, 1 tsp Smoked Paprika, 1 tsp Black Pepper, Salt to Taste
Heat the oil over medium-high heat in a Dutch oven or multicooker (sauté setting on multicooker). If you are using a slow cooker, Heat the oil in a large skillet on your stove. You can add everything from the skillet into the slow cooker later. 1 Tbsp Vegetable Oil
Sear the roast in the oil on all sides. 4-5 minutes per side, including the actual sides of the roast. Remove and set aside. Add the onion, celery, and (optional) bell pepper to the oil and sauté for 3-4 minutes until they begin to soften.
1 Medium Onion, Cut into 1/2 inch think slices, 2 Ribs Celery, Cut into 1 inch chunks, 1 Green Bell Pepper, Cut into 1 inch chunks
Add the butter and cook until melted. Then stir in the flour, coating the vegetables.
4 Tbsp Butter, 4 Tbsp All-Purpose Flour
Cook, stirring often, for 2-3 minutes, until the flour begins to darken to a golden color (this is the very beginnings of a roux).
Deglaze the pan by pouring in the beer and broth, and scraping up the browned bits from the bottom.
1 C Beef Broth, 1 C Lager Beer
If using a slow cooker, move this gravy from your skillet to your slow cooker now.
Add the Worcestershire sauce, garlic and bay leaf. If using low sodium broth, add another 1/2 tsp of salt.
4 Cloves Garlic, Smashed, 2 Tbsp Worcestershire Sauce, 1 Bay Leaf
If using a Dutch oven, set your actual oven to 300°F.
Layer the potatoes in the bottom with the other vegetables and place the roast on top (pour in any juices that the roast released while resting).Note: if you like a little more bite to your potatoes, add them (on top) halfway through cooking. I personally enjoy the creamy texture they take on by cooking the entire time. 1-2 Lbs Baby Potatoes, Kept Whole
Sprinkle with your remaining seasonings and place the sausage on top.
12 Oz. Andouille or Smoked Sausage, Cut into 1 inch chunks
Time to slow cook. Cook until the sausage and potatoes are cooked through, and the roast is fork tender. For the multicooker and slow cooker, set to slow cook on low for 8-10 hours, or high for 4.5-6.5 hours. The longer the better, but definitely aim for the higher end of the range as the size of the roast increases.With a Dutch oven, cook at 300°F for the following:2 lb roast - 2.5 to 3 hours3 lb roast - 3.5 to 4 hours4 lb roast - 4.5-5 hours To finish, remove the roast, sausage and potatoes from the pot. Let the roast rest 10 minutes before slicing, shredding or breaking into chunks (my favorite).
If you need to thicken the gravy/vegetables, cook uncovered for a few more minutes to help reduce. If you're using a slow cooker, you may need to move the gravy back to a skillet for this. If you really need to thicken it, you can add a slurry of another Tbsp flour and a Tbsp of water. If you need to thin out the gravy, you can add a little more beef broth or beer. Check the gravy for salt and pepper before pouring over the roast, sausage and potatoes. Serve this with mashed potatoes, egg noodles, or even some creamy grits!
