Ingredients

Beef Tenderloin (about 2 lbs): The star of the show—tender, juicy, and perfect for stuffing.
Lump crab meat (1 cup): Picked carefully to keep it shell-free and full of sweet flavor.
Breadcrumbs (¼ cup): Adds just enough texture to keep the crab filling together.
Mayonnaise (2 tablespoons): Keeps the stuffing moist and creamy.
Dijon mustard (1 tablespoon): Adds a subtle tangy kick.
Fresh parsley (1 tablespoon, chopped): Brightens the crab filling with fresh herbal notes.
Salt and pepper: To taste, seasoning both the filling and the beef.
Olive oil (2 tablespoons): For that perfect sear on your tenderloin.
Unsalted butter (½ cup, melted): Essential for the silky Béarnaise sauce.
White wine vinegar (2 tablespoons): Adds acidity and depth to the sauce.
Fresh tarragon (2 tablespoons, chopped): The signature herb in Béarnaise that’s fragrant and delicious.
Egg yolks (2): The base of your sauce, creating that rich, creamy texture.

How to Make Crab-Stuffed Beef Tenderloin with Béarnaise Bliss

Ready to wow your dinner guests? Let’s break it down step by step. Don’t worry, I’ll guide you through so you get that perfect balance of flavors and textures.

Preheat your oven to 400°F (200°C). This gets your cooking space ready for roasting the tenderloin just right.
Butterfly the beef tenderloin by slicing it horizontally down the center, but don’t cut all the way through—think of opening a book.
In a bowl, gently mix the lump crab meat, breadcrumbs, mayonnaise, Dijon mustard, chopped parsley, salt, and pepper. This is your flavorful stuffing that’s creamy yet holds its shape.
Spread the crab mixture evenly over the inside of the butterflied beef. Take your time here—this layer is what makes the dish truly special.
Roll the tenderloin back to its original shape carefully and tie it with kitchen twine at intervals. This keeps everything snug and cooks evenly.
Season the outside of the tenderloin with salt and pepper to taste.
Heat olive oil in an oven-safe skillet over medium-high heat. Sear the beef on all sides until beautifully browned, about 2-3 minutes per side. This step locks in flavors and gives you a gorgeous crust.
Transfer the skillet to your preheated oven and roast for 25-30 minutes. You’re aiming for an internal temperature of 135°F (57°C) for a perfect medium-rare finish.
Once done, remove the tenderloin and let it rest for 10 minutes. Resting lets the juices settle so every slice is juicy and tender.
While resting, whisk together white wine vinegar and chopped tarragon in a small saucepan over medium heat until it reduces by half. Let it cool slightly off the heat.
In a blender or food processor, blend the egg yolks until frothy. Then, with the blender running, slowly pour in the melted butter in a steady stream until the sauce thickens beautifully.
Add the reduced tarragon and vinegar mixture to the blender and blend until smooth and creamy. Season with salt and pepper to taste.
Remove the kitchen twine from your beef tenderloin, then slice into thick, juicy rounds.
Arrange the slices on a serving platter, drizzle generously with your homemade Béarnaise sauce, and garnish with a little extra chopped parsley if you’d like.
Serve immediately and bask in the compliments that are sure to come your way!

Substitutions & Additions

Want to switch things up or tailor this dish to what you have on hand? Here are some ideas:

Crab meat swap: If fresh lump crab isn’t available, canned crab meat works in a pinch, or try shrimp for a different seafood twist.
Breadcrumb alternatives: Use panko for extra crunch or crushed crackers for a bit more flavor.
Herb variations: Swap fresh parsley for chives or dill to add a new herbal note.
Béarnaise tweaks: If you’re short on tarragon, fresh thyme or basil can add a lovely twist to your sauce.
Make it surf and turf deluxe: Serve alongside buttery lobster tails or grilled shrimp skewers for a full seafood feast.

Tips for Success

Don’t skip resting: Letting the beef rest after roasting is key to juicy slices.
Keep an eye on temperature: Use a meat thermometer to nail that perfect medium-rare without guesswork.
Tie it tight: Tying the tenderloin with kitchen twine keeps the stuffing secure and the shape uniform.
Prep ahead: You can prepare the crab stuffing a day before to save time. Just keep it covered in the fridge.
Perfect your Béarnaise: If you’re nervous about the sauce, try making a simpler hollandaise first, like the one in my easy homemade cream cheese post, which shares some helpful tips on emulsification.

How to Store Crab-Stuffed Beef Tenderloin with Béarnaise Bliss

If you have leftovers (which I hope you do!), here’s how to keep them fresh and tasty:

Wrap the sliced tenderloin tightly in aluminum foil or place it in an airtight container.
Store in the refrigerator for up to 3 days.
Reheat gently in the oven at 300°F wrapped in foil to avoid drying out.
For the Béarnaise sauce, it’s best served fresh but can be stored in an airtight container in the fridge for 1-2 days. Reheat carefully over low heat or in a warm water bath to keep it smooth.

FAQs

Q: Can I prepare the beef tenderloin stuffed the night before?

A: Absolutely! You can butterfly, stuff, and tie the tenderloin the night before. Just keep it refrigerated and let it come to room temperature before cooking.

Q: What if I don’t have a blender for the Béarnaise sauce?

A: You can whisk it by hand over a double boiler, but be patient and whisk constantly to prevent the eggs from scrambling. Or try a simple hollandaise as an easier alternative.

Q: Can I use a different cut of beef?

A: Beef tenderloin is ideal for its tenderness and shape, but a top sirloin roast could work if you butterfly it carefully.

Q: How spicy is the crab stuffing?

A: This recipe isn’t spicy, but if you like a little heat, add a pinch of cayenne or some finely chopped jalapeño to the crab mixture.

For a perfect ending to your meal, consider pairing this dish with some buttery melt-in-mouth biscuits from my buttery melt-in-mouth biscuits recipe. They soak up the Béarnaise beautifully!
