Ladle this 1 mixture over raw beef into a slow cooker for a hearty dish that's impossibly comforting

This slow cooker creamy Irish whiskey beef fettuccine is the kind of hearty, comforting dish that earns a permanent place in a weeknight rotation. It leans on a single, flavor-packed mixture—Irish whiskey, beef broth, heavy cream, whole grain mustard, and fresh thyme—that you simply ladle over raw beef sirloin tips and dry fettuccine in the slow cooker. The inspiration here is part Irish pub comfort food, part Midwestern casserole practicality: rich, savory, and deeply satisfying with almost no hands-on work once everything is in the pot.

Serve this creamy Irish whiskey beef fettuccine straight from the slow cooker into warm bowls, topped with a little extra fresh thyme or chopped parsley for color. A crisp green salad with a bright vinaigrette balances the richness nicely, and a side of crusty bread or garlic toast helps mop up the sauce. If you enjoy wine, a medium-bodied red like a Merlot or an easygoing Pinot Noir pairs well, or lean into the theme with a small glass of Irish whiskey on the side for sipping.

Servings: 6

1 1/2 pounds beef sirloin tips, trimmed and cut into 1 1/2-inch pieces

Lightly grease the inside of a 5- to 6-quart slow cooker with olive oil or a quick spritz of nonstick spray to help prevent sticking and make cleanup easier.

Scatter the raw beef sirloin tips evenly over the bottom of the slow cooker in a single, fairly even layer. Season the beef lightly with a pinch of salt and pepper.

Break the dry fettuccine in half so it fits more easily in the slow cooker. Arrange the fettuccine over and around the beef, fanning it slightly so the strands are not tightly clumped together. This helps the pasta cook more evenly in the sauce.

In a medium mixing bowl or large measuring cup, whisk together the beef broth, Irish whiskey, heavy cream, whole grain mustard, Dijon mustard (if using), fresh thyme leaves, 1 teaspoon kosher salt, 1/2 teaspoon black pepper, minced garlic, and chopped onion until the mixture is well combined and smooth. This is your single flavor base.

If you prefer a slightly thicker, clingier sauce from the start, whisk the cornstarch and cold water together in a small bowl to make a slurry, then whisk that into the whiskey-cream mixture until fully incorporated.

Holding the bowl over the slow cooker, ladle this one combined mixture slowly and evenly over the raw beef sirloin tips and dry fettuccine, making sure to moisten as much of the pasta as possible. The liquid will not fully cover everything, but the pasta will soften and sink as it cooks.

Cover the slow cooker with the lid and cook on LOW for 3 1/2 to 4 1/2 hours, or on HIGH for 2 to 2 1/2 hours. About halfway through the cooking time, gently use tongs to separate and turn the fettuccine so all the strands get access to the sauce, being careful not to break up the beef too much.

Check the pasta for doneness near the earlier end of the cooking window. The fettuccine should be tender but still slightly firm to the bite, and the beef should be very tender. If the sauce looks thin, keep the lid off for the last 15 to 20 minutes on HIGH to reduce slightly, or stir in an extra tablespoon of grated Parmesan to help thicken.

Once the beef and pasta are cooked to your liking, stir in the grated Parmesan cheese until melted and smooth. If you want a richer finish, add the butter and stir until it melts into the sauce. Taste and adjust seasoning with additional salt and pepper as needed.

Let the dish sit, covered, for 5 to 10 minutes on the Warm setting to allow the sauce to settle and cling to the fettuccine. Serve hot, garnished with extra fresh thyme or chopped parsley and more Parmesan at the table.

For a slightly lighter version, you can substitute half-and-half for half of the heavy cream, understanding the sauce will be a bit less rich and slightly thinner. If you prefer not to cook with alcohol, replace the Irish whiskey with additional beef broth and a teaspoon of Worcestershire sauce; you lose the distinct whiskey note but keep a deep, savory flavor. To add more vegetables, layer 1 to 1 1/2 cups of sliced mushrooms or thinly sliced bell peppers over the beef before adding the fettuccine, or stir in a couple of handfuls of baby spinach during the last 10 minutes of cooking until just wilted. For a spicier take, whisk 1/4 to 1/2 teaspoon crushed red pepper flakes into the whiskey-cream mixture. If you only have stew meat instead of sirloin tips, it will work, but plan on the longer end of the cooking time so it becomes tender. You can also swap the fettuccine for another long pasta such as linguine or even wide egg noodles; just keep an eye on the timing, as thinner noodles may cook a bit faster. Finally, if you like a more pronounced mustard profile, increase the whole grain mustard to 4 tablespoons and omit the Dijon, letting the texture and pop of the mustard seeds stand out in the sauce.
