Ingredients for Filet Mignon Roast Crock Pot
Quality beef plus a few aromatics. That is all you need for this showstopper.
| Ingredient | Amount | Notes |
|---|---|---|
| Filet Mignon Roast 🥩 | 2 lb | Whole piece, trimmed of excess fat |
| Kosher Salt 🧂 | 1 ½ tsp | Divided for seasoning and searing |
| Black Pepper 🌶️ | 1 tsp | Freshly ground preferred |
| Garlic Cloves 🧄 | 4 cloves | Minced for robust flavor |
| Fresh Rosemary 🌿 | 2 tbsp | Chopped, stems discarded |
| Fresh Thyme 🍃 | 2 tbsp | Chopped, stems discarded |
| Olive Oil 🫒 | 2 tbsp | For searing the roast |
| Beef Broth 💧 | 1 cup | Low-sodium preferred |
| Red Wine 🍷 | ½ cup | Dry variety for depth |
| Unsalted Butter 🧈 | 2 tbsp | For finishing the roast |
| Yellow Onion 🧅 | 1 whole | Sliced for aromatic base |
| Carrots 🥕 | 3 whole | Peeled and cut into chunks |
| Celery Stalks 🥬 | 2 whole | Cut into large pieces |
The filet mignon is the star here—splurge on prime grade if you can. Whole Foods or Costco have great options, but your local butcher will hook you up with the best cut. Look for even marbling and a bright red color. The roast should be about 2-3 inches thick for even cooking. Don’t skip the searing step (cast iron works best) or you’ll lose that deep, caramelized crust.
No red wine? Swap in beef broth with a splash of balsamic vinegar. Fresh herbs are ideal, but dried at half the amount works in a pinch. If you’re avoiding alcohol, just double the beef broth. The butter at the end is non-negotiable—it adds that final touch of richness. For extra flavor, toss in a bay leaf with the aromatics.
Leftovers keep for 4-5 days in the fridge, but honestly, this disappears fast. You can freeze portions for up to 3 months—just thaw overnight before reheating. Slice against the grain when serving for maximum tenderness.

Step-by-Step Instructions for Filet Mignon Roast Crock Pot
This slow cooker method delivers tender, elegant results with minimal hands-on time.
Step 1: Sear the Filet Mignon Roast
Pat the 2 lb Filet Mignon Roast dry with paper towels and season generously with 1 tsp Kosher Salt and 1 tsp Black Pepper. Heat the 2 tbsp Olive Oil in a large skillet over medium-high heat until shimmering.
Sear the roast on all sides for 2-3 minutes per side until deeply browned. This step creates a flavorful crust and locks in juices. Don’t rush—wait until each side develops a rich golden-brown color before turning.
Step 2: Prepare the Aromatic Base
Slice the 1 whole Yellow Onion and chop the 3 whole Carrots and 2 whole Celery Stalks into large chunks. Mince the 4 cloves Garlic Cloves and chop the 2 tbsp Fresh Rosemary and 2 tbsp Fresh Thyme.
Place the vegetables in the bottom of your slow cooker. This creates a natural rack for the roast to sit on, ensuring even cooking and infusing the meat with aromatic flavors. Sprinkle the remaining 0.5 tsp Kosher Salt over the vegetables.
Step 3: Slow Cook with Liquids
Place the seared roast on top of the vegetables in the slow cooker. Pour in the 1 cup Beef Broth and 0.5 cup Red Wine. The liquid should come about halfway up the roast—add a splash of water if needed to reach this level.
Cover and cook on low heat for 6-7 hours or on high heat for 4-5 hours. The roast is done when an instant-read thermometer inserted into the thickest part reads 135°F for medium-rare. The meat should feel tender when pierced with a fork.
Step 4: Rest and Finish with Butter
Carefully transfer the roast to a cutting board and tent loosely with foil. Let it rest for 15 minutes—this allows the juices to redistribute, ensuring every slice is moist and flavorful.
While the roast rests, stir the 2 tbsp Unsalted Butter into the cooking liquid in the slow cooker to create a rich, silky sauce. Slice the roast against the grain into thick slices and serve with the sauce spooned over the top.
Pro Tips For Making Filet Mignon Roast Crock Pot
- Sear First: I learned this the hard way—browning the filet mignon roast in a hot pan for 2-3 minutes per side before it goes into the crock pot locks in juices and adds depth of flavor.
- Use Fresh Rosemary: Dried rosemary just doesn’t cut it here; finely chop 2-3 sprigs of fresh rosemary and rub it into the meat with the garlic for a brighter, more aromatic result.
- Don’t Overcrowd: Resist the urge to cram the crock pot with veggies or other ingredients—give the roast space so the heat circulates evenly and cooks it properly.
- Rest Before Slicing: After cooking, let the roast rest under foil for at least 10 minutes—this keeps all the juices inside where they belong instead of on the cutting board.
Make-Ahead Tips for This Dish
Prep the Night Before
Trim and season your 2 lb Filet Mignon Roast the evening before cooking. Store it uncovered in the fridge to develop a better sear later. Chop all vegetables and herbs, keeping them in separate containers.
Sear in Advance
If you’re short on morning time, sear the roast the night before. Let it cool completely, then refrigerate in a sealed container. This saves 10-15 minutes on cooking day while maintaining flavor.
Slow Cooker Setup
Layer your vegetables and herbs in the crock pot insert the night before. Cover and refrigerate. In the morning, just add the seared roast and liquids, then start cooking. This cuts morning prep to under 5 minutes. 💡
Liquid Prep
Mix your 1 cup Beef Broth and 0.5 cup Red Wine in a measuring cup and refrigerate overnight. Cold liquids help maintain food safety while the crock pot heats up.
Timing Strategy
For a 6 PM dinner, start on low at 10 AM. If using high heat, begin at 1 PM. Set a phone reminder for the halfway point to check liquid levels.
Post-Cook Rest
The roast can rest covered in the crock pot for up to 30 minutes after cooking. This gives you a buffer if guests are running late without sacrificing quality. 🔥

Frequently Asked Questions
Can I use a different cut of beef?
Stick with tender cuts like ribeye or tenderloin for best results. Tougher cuts won’t achieve the same melt-in-your-mouth texture in a crock pot.
What if I don’t have red wine?
Substitute with extra beef broth plus 1 tbsp balsamic vinegar for similar depth. Apple cider vinegar works in a pinch too.
How do I know when it’s done?
Use a meat thermometer—135°F for medium-rare, 145°F for medium. The meat should pull apart easily with a fork.
Can I add potatoes to the crock pot?
Yes, but add them during the last 2-3 hours to prevent mushiness. Use baby potatoes or large chunks for best texture.
