Key Ingredient Notes
The Star: Leftover Prime Rib
Your leftover prime rib is the hero here, so treat it with respect! For the best results, ensure your prime rib is sliced thinly against the grain. This maximizes tenderness and ensures each bite is easy to manage. If your prime rib is already cold from the fridge, don’t worry – a quick sear or gentle warming in the pan with the onions will bring it back to life. Avoid overcooking it during this stage, as prime rib is best served medium-rare to medium for optimal flavor and texture. This is crucial for any of the best leftover prime rib recipes.
Sweet & Savory Depth: Caramelized Onions
Caramelized onions are the secret weapon that takes this sandwich from good to gourmet. The key to truly delicious caramelized onions is patience. Don’t rush the process! Low heat and slow cooking allow the natural sugars in the onions to develop, resulting in a deep, sweet, and savory flavor that perfectly complements the rich prime rib. A touch of balsamic vinegar or a pinch of sugar can help deepen their color and flavor even further. They add an essential layer of complexity to these prime rib recipes.
The Kick: Horseradish Cream
A good horseradish cream is non-negotiable for prime rib. It provides a delightful piquant counterpoint to the richness of the meat and the sweetness of the onions. You can adjust the amount of horseradish to your liking – more for a fiery kick, less for a subtle tang. Using freshly grated horseradish will give you the most vibrant flavor, but prepared horseradish works perfectly well too. Just be sure to use a good quality one. This creamy, spicy element is what truly makes this one of the stand-out leftover prime rib recipes.
Step-by-Step Guide with Pro Tips
Here’s how to transform your holiday remnants into an unforgettable meal, easily one of the best leftover prime rib recipes you’ll ever make.
Prepare the Horseradish Cream
In a small bowl, combine mayonnaise, sour cream, prepared horseradish (adjust to taste), fresh chives (if using), and a squeeze of lemon juice. Season with salt and black pepper. Stir until well combined. Cover and refrigerate until ready to use. This can be made ahead of time to allow flavors to meld.
Caramelize the Onions
Heat olive oil in a large skillet or frying pan over medium-low heat. Add the thinly sliced onions and a pinch of salt. Cook, stirring occasionally, for 20-30 minutes, or until the onions are deeply golden brown and very tender. If they start to dry out, add a tablespoon of water or beef broth. For an extra layer of flavor, you can deglaze the pan with a splash of red wine or balsamic vinegar in the last few minutes of cooking.
Warm the Prime Rib
While the onions are caramelizing, gently warm your prime rib slices. You can either add them directly to the pan with the onions for the last 5 minutes of cooking, or lightly sear them in a separate hot pan for 1-2 minutes per side until just warmed through. Be careful not to overcook, as this can make the prime rib tough. You want to preserve that beautiful medium-rare or medium doneness. This step is key to making these some of the best leftover prime rib recipes.
Assemble the Sandwiches
Lightly butter one side of each bread slice (or brush with olive oil). In a separate clean pan or on a griddle, toast the bread over medium heat until golden brown and crispy. Once toasted, spread a generous layer of horseradish cream on the unbuttered side of each slice. Pile a desired amount of warm prime rib onto one slice of bread, followed by a generous spoonful of caramelized onions. Top with the other slice of bread.
Serve and Enjoy!
Slice the sandwiches in half, if desired, and serve immediately. These are best enjoyed warm. Consider serving with a side of au jus for dipping, if you have any leftover from your original prime rib roast. Don’t forget to store any extra prime rib or ingredients in airtight Basics Glass Food Storage containers for future leftover prime rib recipes!
Variations & Serving Suggestions
The beauty of leftover prime rib recipes is their versatility. Here are some ideas to make this sandwich your own:
- Cheesy Goodness: Add a slice of Provolone, Swiss, or even a sharp cheddar to the sandwich while the prime rib is warming. The melting cheese adds another layer of decadence.
- Spicy Kick: For those who love heat, add a few slices of pickled jalapeños or a dash of hot sauce to your horseradish cream.
- Greens Power: Incorporate some fresh arugula, spinach, or even some Sautéed Dandelion Greens with Garlic & Lemon for a peppery bite and a touch of freshness.
- Different Breads: While a crusty artisan bread is fantastic, don’t hesitate to experiment with ciabatta, sourdough, or even a soft brioche bun for a different experience.
- Serving Sides: These sandwiches pair wonderfully with a simple green salad, a cup of tomato soup, or some crispy potato chips. For a truly hearty meal, consider serving alongside a comforting bowl of The Ultimate Cozy Crockpot Ham and Bean Soup.
- Open-Faced Option: For a lighter take on leftover prime rib recipes, serve it open-faced on toasted bread, drizzled with a little extra au jus.

How do you reheat prime rib for sandwiches without drying it out?

Consider adding a slice of your favorite melting cheese (Provolone, Swiss, or cheddar), fresh arugula for a peppery bite, pickled jalapeu00f1os for heat, or even a fried egg for a hearty breakfast-for-dinner option.
