Step-by-Step Instructions for Our Best Leftover Prime Rib Recipes: Creamed Spinach Style

Okay, here’s the fun part! Turning those pricey leftovers into this amazing skillet meal is easier than you think. We are moving fast, but we need to build that steakhouse flavor correctly so this dish earns its spot in Our Best Leftover Prime Rib Recipes. Don’t rush the simmering time, that’s where the magic happens to thicken up that sauce! If you love skillet meals packed with flavor, once you finish this, you might want to check out my recipe for Garlic Mushroom Chicken Casserole!

Building the Flavor Base and Thickening the Gravy

First things first, get that olive oil hot in your big deep pan over medium-high heat. Toss in your minced shallot and garlic—we just want them happy and soft for about a minute. Then, drop in the butter and let it melt. Once it’s sizzling happily, whisk in your flour right away. You need to cook that flour out for a minute until it disappears into the fat; this is our thickening agent!

Toss in your mushrooms and all those yummy dried herbs and spices, stirring well. Now pour in that beef broth, the Worcestershire sauce, and that slightly coarse Dijon mustard. Bring this whole mixture up to a gentle simmer. I always recommend keeping an eye on it for about 10 minutes. If you happened to save any of your original Gravy & Au Jus, now is the time to stir in a spoonful or two for extra depth! Keep the heat low so it can thicken slowly; we want a nice coat, not cement.

Incorporating the Prime Rib and Finishing the Dish

Once your gravy is looking rich and slightly coating the back of your spoon, it’s time for the star! Gently drop in those 2-inch strips of leftover prime rib. We are only heating the meat through here, friends—seriously, only 2 or 3 minutes tops! Overcooking leftover steak is a crime against beef and will make it tough. That’s why quick meals are the best of Our Best Leftover Prime Rib Recipes.

When the meat is just warmed through, take the pan completely off the heat. This is a crucial step! Stir in that quarter cup of sour cream until everything is smooth and creamy. If you leave it on the burner, the sour cream might get grainy, and we definitely don’t want that. Serve it immediately over those noodles—or whatever base you choose!

Tips for Success with Leftover Prime Rib Recipes

Making a successful leftover meal means avoiding common pitfalls, and I always have a few tricks up my sleeve to ensure this creamy dish comes out perfect every time. Getting the texture right is everything when dealing with pre-cooked meat! Trust me, these little bits of knowledge save you from disappointment.

First, about that sour cream: always, and I mean always, remove the pan from the heat before stirring it in. If you boil sour cream, it separates faster than you can say Prime Rib. We want luscious silkiness, not chunky soup!

Second, if you are watching carbs like I usually am, ditch those egg noodles. Instead, serve this incredible sauce over some creamy mashed potatoes (like my Mashed Potato Puff Bites!) or, even better, use a low-carb base. A bed of steamed broccoli or maybe a warm Cauliflower Gratin would be heavenly here. The rich beef flavor stands up beautifully to sharp, cheesy sides.

Finally, if your Gravy & Au Jus was particularly salty, go easy on adding extra salt during the initial seasoning phase. Taste test after adding the beef! Better too bland than too powerful, right?

Serving Suggestions for Our Best Leftover Prime Rib Recipes

Okay, this creamy, savory masterpiece is definitely the main event, but what are we putting this gorgeous creation on top of? Since this recipe is technically scaled for just one lucky person (though you should totally multiply it!), you have the freedom to pair it perfectly. This dish is so rich, it screams for something neutral beneath it to catch all that wonderful sauce.

If you’re sticking to the traditional comfort route, you absolutely need something starchy and soft. My go-to—even when I’m not focused on low-carb meals—is a mound of creamy mashed potatoes. Forget the leftover Mashed Potatoes from the night before; make a fresh, small batch so they are piping hot! You can look at my recipe for Mashed Potato Puff Bites for a fun twist!

For those of you keeping it low-carb, think about serving this over a bed of steamed cauliflower rice or even thick slices of roasted celery root. These act as fantastic sponges for the sauce while keeping the meal feeling hearty. This is truly one of Our Best Leftover Prime Rib Recipes because it adapts to whatever Holiday Sides you have lingering!

Another simple idea is swapping noodles for polenta if you have some on hand, or just diving right in with some thick-cut toast to soak up every last drop! That’s how you know you’ve made a winner.

Storage and Reheating Instructions for Leftover Prime Rib Recipes

Listen, if you don’t eat this entire batch of creamy goodness in one sitting (and trust me, I’ve tried!), knowing how to store it right is key. Keep any leftovers in a completely airtight container in the fridge. It should stay fresh for about three to four days. We want that prime rib soft, not rubbery, when we reheat it, so don’t blast it in the microwave!

When you’re ready for round two of these amazing Leftover Prime Rib Recipes, reheat it low and slow on the stovetop. Add just a tiny splash of beef broth or water to the pan before warming it up. That steam keeps the meat lovely and tender. This simple technique ensures your reheated creamy dish is just as comforting as the first serving from our collection of Our Best Leftover Prime Rib Recipes.

Frequently Asked Questions About Repurposing Prime Rib

I get so many questions every time I share one of these easy ways to use up that amazing leftover prime rib! It’s comforting to know so many of you hate waste as much as I do. Here are a few things people ask me most often when they’re looking through my collection of Leftover Prime Rib Recipes.

Can I use leftover Roast Turkey instead of Prime Rib?

That’s a great question! Yes, you absolutely can substitute the prime rib with leftover Roast Turkey or even leftover Holiday Ham if that’s what you have hiding in the fridge. You’ll still get a super creamy dish, but the flavor profile will obviously shift slightly—you’ll be moving from a rich beef flavor toward something a little milder or saltier, depending on the ham. Just be mindful of the salt content in the broth if you use ham!

How do I make this recipe low-carb or Keto-friendly?

That’s my favorite way to eat it! The recipe I shared above is easy to modify for lower carbs. The biggest change you need to make is ditching the egg noodles listed in the recipe data! Instead, serve that creamy sauce and perfectly heated beef slices over steamed cauliflower rice or spiralized zucchini noodles. Honestly, zucchini noodles are amazing because they warm up quickly right in the sauce.

What if I don’t have mushrooms?

No stress at all! While the mushrooms add an earthy touch that pairs well with beef, they are totally optional. You can skip them altogether, or if you want to round out the texture, toss in half a cup of frozen peas or maybe some finely diced celery when you are sautéing the shallots at the beginning. It just needs a little crunch or earthiness!

Beyond Creamed Spinach: More Ideas for Our Best Leftover Prime Rib Recipes

I’m so glad we found the perfect creamy skillet meal, but wow, there are so many other ways to make those beef remnants sing!

Another brilliant use in my rotation of Our Best Leftover Prime Rib Recipes is adding thin strips right into a rich soup base. Think about simmering that beef with some carrots, celery, and maybe some pearl onions—it makes for the heartiest meal ever. Or, for something totally different, you can use it in a quick beef Manhattan, which is so comforting. You can find my specific recipe for a Slow Cooker Beef Manhattan Sandwich if you want a completely different texture profile. See? Your leftover Prime Rib is versatile!

Keep that in mind when you’re scaling up so you don’t run out of broth!

Now, for the numbers stuff. The nutrition breakdown below is only an estimate because remember, we are using leftover prime rib, and the fat content in roast drippings can seriously change things! But based on the specific measurements listed here, this is what that single serving provides:
