Instructions

Slow Cooker Tips For Perfect Results

For the best set and forget crockpot dinners, a few little tips go a long way. Don’t lift the lid during cooking! I know it’s tempting to peek, but you let out precious heat and steam, which can really extend the cooking time. For a richer sauce, you can quickly sear the beef cubes in a hot skillet before adding them to the crockpot. It adds another layer of flavor, but honestly? It’s still incredible without that step if you’re truly pressed for time. Make sure your cornstarch slurry is cold; mixing it with cold water prevents lumps from forming in your beautiful sauce. And finally, if your slow cooker runs hot, check for doneness an hour earlier to avoid overcooking.

Variations & Substitutions

This recipe is wonderfully adaptable. Not a beef fan? Swap it out for two pounds of boneless, skinless chicken thighs for a fantastic chicken crockpot recipes twist. For a gluten-free version, use tamari instead of soy sauce and serve over your favorite gluten-free pasta or mashed potatoes. Out of cremini mushrooms? White button mushrooms work just fine. And if you want to sneak in some veggies, toss in a handful of baby carrots or frozen peas during the last 30 minutes of cooking.

Serving Ideas & Pairings

This meal is a complete comfort food feast on its own, but it’s also great with a simple side. A crisp green salad with a light vinaigrette helps cut through the richness. Buttery steamed green beans or roasted broccoli are also fantastic partners. For a heartier spread, a slice of crusty bread is perfect for sopping up every last bit of that incredible garlic butter sauce. So good.

Storage & Reheating

Let any leftovers cool completely before storing. They’ll keep in an airtight container in the fridge for 3-4 days. You can also freeze it for up to 3 months. To reheat, thaw overnight in the fridge if frozen. Gently warm portions in a saucepan over medium-low heat, stirring occasionally, until heated through. You might need to add a tiny splash of broth or water to loosen the sauce back up. I don’t recommend freezing the cooked noodles, as they can become mushy—just cook fresh noodles when you’re ready to enjoy again.
