How to Make Slow-Cooker Sunday Sauce
Step 1: Build the Slow Cooker Base
Add the crushed tomatoes directly to a 6–8 quart slow cooker. Nestle the basil sprigs into the tomatoes so their flavor gently infuses the sauce over time. Season the beef shoulder generously with salt and black pepper on all sides—this early seasoning ensures the meat is flavorful all the way through.
Step 2: Brown the beef and Sausage
Heat 2 tablespoons of olive oil in a large Dutch oven over medium-high heat. When the oil shimmers, add the beef shoulder pieces in batches, making sure not to overcrowd the pan. Brown the beef on two sides until a deep golden crust forms, about 8–10 minutes total. This step adds essential flavor through caramelization. Transfer the beef to the slow cooker as each batch finishes.
In the same pot, brown the Italian sausages until nicely colored on all sides, about 4–6 minutes. You’re not cooking them through—just developing flavor. Move the sausages to the slow cooker.
Step 3: Create the Aromatic Base
Lower the heat to medium-low and add the remaining olive oil if the pot looks dry. Add the chopped onion and garlic, seasoning lightly with salt and pepper. Cook until the onion softens and turns translucent, 2–4 minutes. Stir frequently to avoid burning.
Pour in the red Jus de raisin and use a wooden spoon to scrape up the browned bits stuck to the bottom of the pot—this is where a lot of flavor lives. Let the Jus de raisin simmer until almost completely evaporated, concentrating its richness. Transfer this onion-Jus de raisin mixture into the slow cooker and gently stir to combine. Place the meatballs on top, even if some sit above the sauce—they’ll settle as everything cooks.
Cover and cook on LOW for 6–8 hours, until the beef shoulder easily shreds with a fork.
Step 4: Cook the Pasta and Finish the Sauce
When ready to serve, bring a large pot of generously salted water to a rolling boil. Cook the pasta according to package instructions until al dente.
While the pasta cooks, remove the sausage and beef from the slow cooker. Slice the sausage and shred the beef using two forks. Set aside.
Reserve ½ cup of pasta water, then drain the pasta and return it to the pot. Over medium heat, toss the pasta with about 4 cups of sauce, adding pasta water gradually until the sauce clings beautifully to each noodle. Some meatballs may sneak into the pasta pot—that’s perfectly fine.
Return the sliced sausage and shredded beef to the remaining sauce in the slow cooker.
Step 5: Serve and Enjoy
Divide the sauced pasta among bowls. Top each serving with pieces of sausage, beef , and meatballs. Finish with freshly grated Parmesan or pecorino. Serve extra sauce and meat at the table for anyone who wants more.
