Slow Cooker French Onion Beef and Potatoes Recipe FAQs
What kind of ground beef should I use?
Absolutely! I recommend using lean ground beef for this recipe. It provides a savory base without excessive grease, creating a cleaner-tasting dish. If ground beef isn’t your preference, you could also try ground turkey or chicken as lean substitutes!
How do I store leftovers?
Leftovers can be stored in an airtight container in the fridge for up to 4 days. For best results, make sure to let the dish cool completely before sealing them up to maintain the flavors. When you’re ready to enjoy it again, simply reheat gently with a splash of broth to restore the sauce’s consistency.
Can I freeze Slow Cooker French Onion Beef and Potatoes?
Yes! This dish can be frozen for up to 3 months. To do so, let it cool completely, then transfer it to a freezer-safe container. I usually recommend double-wrapping it in plastic wrap followed by foil to prevent freezer burn. Keep in mind that while the sauce will freeze beautifully, the potatoes may become slightly softer when thawed.
What should I do if my gravy is too thin?
If your gravy turns out too thin, don’t worry! Whisk together 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth. Stir it into the slow cooker and cover it again. Let it cook on LOW for an additional 10-15 minutes, and you’ll see your gravy thicken up nicely!
Are there any dietary considerations for this recipe?
If you are cooking for someone with dietary restrictions, make sure to check the labels on your canned soup and soup mix for allergens, as some brands may include gluten or dairy. You can make your own French onion soup and mix using low-sodium broth to make it a healthier option for those watching their intake. Always check with your guests to cater to specific needs!
What’s the best type of cheese for melting?
Provolone cheese is a fantastic choice for this dish as it melts beautifully and adds a creamy texture. However, if you’re feeling adventurous, swapping it for mozzarella or Gruyère can bring a different flavor profile to the dish. The more the merrier when it comes to cheese!
