Ingredients You'll Need
Getting the perfect dip starts with a few simple but crucial ingredients that balance richness, flavor, and texture. Each item plays its part in making this dish irresistibly delicious and easy to put together.
- 12 slices prime rib: The star of the dish, sliced as thin as possible for tender bites that soak up the au jus beautifully.
- 1 package au jus mix: This savory broth is essential for that rich, flavorful dip that makes every bite juicy and satisfying.
- 4 French rolls: Crusty but soft, these rolls hold the beef and cheese perfectly without getting soggy too fast.
- ¼ cup butter: Adds a golden crispness and a luscious buttery flavor when broiled on the bread.
- ½ teaspoon garlic powder: Brings just the right hint of garlic to the butter spreading, elevating the taste with subtle warmth.
- 8 slices Swiss cheese: Melts into gooey perfection atop the beef, providing creamy richness that complements the savory flavors.
How to Make Leftover Prime Rib Beef Dips Recipe
Step 1: Prepare the Au Jus
Start by making the au jus according to the package directions. Keep it warm on low heat so all those deep, meaty flavors stay ready to soak into your beef. Preheat your oven to broil; you want the perfect balance of toasty and melty later on.
Step 2: Prep the Rolls
Slice the French rolls open almost all the way through—you want to keep one side attached so the roll can cradle the beef and cheese without falling apart. This little trick helps everything stay together when eating.
Step 3: Garlic Butter the Bread
Mix together the butter and garlic powder, then spread this rich, fragrant mixture onto both cut sides of the rolls. When you broil these, the garlic butter will crisp up and give your sandwiches an irresistible crunch and mouthwatering flavor.
Step 4: Broil the Rolls
Place the buttered rolls on a cookie sheet, butter side up, under the broiler. Keep a close eye and broil just until you see the butter turn golden brown and the edges crisp up beautifully. This step adds an amazing texture contrast to your beef dip experience.
Step 5: Soak the Prime Rib in Au Jus
Drop the thin beef slices into the hot au jus, making sure the meat is submerged. Let it warm for about two minutes, allowing the juices to soak in and intensify the flavor of the prime rib.
Step 6: Assemble the Sandwiches
Using tongs, lift the juicy beef slices out of the au jus and let the excess drip back into the pot. Distribute the beef evenly among the prepared rolls. The bread is toasted and buttery, now it’s time to add the tender beef.
Step 7: Add the Swiss Cheese and Melt
Top each sandwich with two slices of Swiss cheese, then place the sandwiches back under the broiler until the cheese melts into gooey perfection. This melt is what brings the whole sandwich together with that melt-in-your-mouth harmony.
Step 8: Serve with Au Jus Bowls
Divide the remaining au jus into four small bowls so everyone can dip their sandwiches and savor that flavorful broth alongside. This interactive element makes the meal fun and extra tasty.
How to Serve Leftover Prime Rib Beef Dips Recipe
Garnishes
Simple garnishes can elevate the experience. Consider freshly chopped parsley or chives sprinkled on top for a fresh pop of color and an herbal contrast to the rich beef. You might also add some caramelized onions inside the sandwich for a sweet complexity.
Side Dishes
Serve your leftover prime rib beef dips alongside crisp, tangy coleslaw or a bright green salad to cut through the richness. A side of crunchy pickles or roasted vegetables makes a lovely addition as well, providing refreshing balance.
Creative Ways to Present
For a fun twist, slice the sandwiches into smaller sliders for parties or appetizers. You can also skip the rolls for an open-faced presentation, layering the beef and cheese on toasted baguette slices and serving the au jus on the side for dipping.
Make Ahead and Storage
Storing Leftovers
If you happen to have some leftover beef dips, store the sandwiches and au jus separately in airtight containers to keep them fresh. Refrigerate for up to three days and ensure you keep the bread separate from any moisture to avoid sogginess.
Freezing
Freezing prepared sandwiches with melted cheese is not recommended as the texture changes. However, you can freeze the au jus broth in ice cube trays for up to three months, which makes it easy to defrost and use with future meals.
Reheating
To reheat, warm the au jus gently on the stove until steaming. Dip the beef slices briefly into the hot broth, then toast your rolls with butter again under the broiler for a minute or two before assembling. Add fresh slices of Swiss cheese and broil until melted to recapture that fresh-baked magic.
FAQs
Can I use a different type of cheese besides Swiss?
Absolutely! While Swiss cheese is traditional for its mild nuttiness and great melt, you can also try provolone, mozzarella, or even a sharp cheddar if you want a bolder flavor. Just pick what melts well and complements your beef.
Is it necessary to broil the rolls, or can I toast them another way?
Broiling gives you the perfect golden buttered crust quickly, but you can also toast the rolls in a skillet over medium heat with the garlic butter if you prefer. The key is to get them crisp and flavorful without drying them out.
What if I don’t have an au jus mix on hand?
You can make a simple au jus using beef broth enhanced with a bit of soy sauce, Worcestershire sauce, and garlic powder. Simmer for a few minutes to deepen the flavors—almost anything savory and beefy works well here.
Can this recipe be made with other leftover beef cuts?
Definitely! While leftover prime rib is ideal, thinly sliced leftover roast beef or sirloin will also work nicely, especially if you warm it gently in the au jus to keep it tender and juicy.
How long can I keep the au jus after making it?
When refrigerated in a sealed container, au jus will stay good for about three to four days. If you want to keep it longer, freezing is your best option and it freezes well in small portions.

Leftover Prime Rib Beef Dips Recipe
- Total Time: 10 minutes
- Yield: 4 servings
Description
This recipe transforms leftover prime rib into delicious French-style beef dip sandwiches. Thinly sliced prime rib is warmed in savory au jus, then nestled inside garlic butter toasted French rolls and topped with melted Swiss cheese for a comforting and flavorful meal perfect for a quick lunch or dinner.
Ingredients
Meat and Cheese
- 12 slices prime rib (slices should be as thin as possible)
- 8 slices Swiss Cheese
Bread
- 4 French rolls
Au Jus and Butter
- 1 package au jus mix
- ¼ cup butter
- ½ teaspoon garlic powder
Instructions
- Prepare Au Jus: Follow the instructions on the au jus mix package to prepare the au jus. Keep it warm over low heat on the stove while you prepare the other ingredients. Preheat your oven to the broil setting.
- Slice Buns: Slice each French roll horizontally, but do not cut all the way through; leave one side attached so the roll can hold the meat and cheese securely.
- Make Garlic Butter: Mix the butter with the garlic powder until well combined. Spread the garlic butter generously on the cut sides of each roll and place them butter side up on a cookie sheet.
- Broil Buns: Place the buns under the broiler until the butter is browned and edges are crispy, about 2-4 minutes. Remove the buns from the oven.
- Warm Beef: Submerge the prime rib slices in the hot au jus to warm the meat, letting it heat for approximately 2 minutes to absorb flavor and become tender.
- Assemble Meat on Rolls: Using tongs, remove the beef slices from the au jus, letting excess liquid drip back into the pot. Evenly divide the warm meat among the four rolls.
- Add Cheese and Broil: Top each assembled sandwich with two slices of Swiss cheese. Return the sandwiches to the oven and broil until the cheese melts and bubbles, about 1-3 minutes.
- Serve with Au Jus: Divide the remaining au jus evenly into four small bowls for dipping, and serve alongside the beef dip sandwiches.
Notes
- Use very thinly sliced prime rib for the best texture and ease of eating.
- Keep a close eye on the buns and sandwiches while broiling to prevent burning.
- Au jus can be made from scratch for a richer flavor if desired.
- If French rolls are not available, crusty sandwich rolls or hoagie buns can be substituted.
- For an extra garlic kick, add minced fresh garlic to the garlic butter mixture.
- Leftover au jus can be refrigerated and used within 3 days.
