You’ll find that the Stuffed Beef Tenderloin with Mushroom Spinach Filling and Red Wine Pan Sauce Recipe is worth every minute spent preparing because the results are nothing short of delicious.

Ingredients You’ll Need

Choosing fresh, quality ingredients makes all the difference here. Each component of the stuffing brings balance – the earthiness of the mushrooms, the brightness of the lemon zest, and the fresh aroma of rosemary. Plus, a good dry red wine elevates the pan sauce dramatically, so don’t skip out on that!

Salted butter: Using room temperature butter in the stuffing helps everything blend beautifully and gives richness to the filling.
Cremini mushrooms: They have a deeper flavor than white mushrooms, which complements the beef perfectly.
Garlic cloves: Fresh garlic adds that punch of savory aroma; don’t substitute with powder here.
Shallots: Two shallots are used – one in the filling and one later for the pan sauce – they’re milder and sweeter than onions.
Crushed red pepper flakes: Just a pinch wakes up the stuffing with a hint of heat.
Kosher salt: Essential for seasoning, and it’s easier to control than table salt.
Black pepper: Freshly ground brings the best flavor.
Baby spinach: Coarsely chopped so it blends well but still has texture in the filling.
Lemon zest and lemon juice: The zest adds a fresh brightness, and juice helps balance the richness.
Seasoned breadcrumbs: These add just enough bulk to the filling and soak up the buttery juices – don’t skip or substitute with plain breadcrumbs unless you season them well.
Grated Parmesan cheese: Parmesan enriches the filling with subtle nuttiness and saltiness.
Fresh rosemary: Finely chopped, it pairs beautifully with both beef and mushrooms.
Beef tenderloin (whole center-cut): Look for a clean, even cut around 4 to 5 pounds – it’s the star of this dish, so quality matters!
Beef broth: Use low-sodium if you prefer more control over saltiness in the pan sauce.
Dry red wine: I recommend a medium-bodied wine like a red blend or Pinot Noir which melts beautifully into the sauce.

Variations

One of the great things about this Stuffed Beef Tenderloin with Mushroom Spinach Filling and Red Wine Pan Sauce Recipe is how adaptable it is. I often tweak the stuffing or sauce depending on what I have or the occasion – feel free to make it your own!

Vegetarian option: I tried swapping the beef for a large portobello mushroom cap stuffed with the filling for a lighter version – while it’s not quite beef tenderloin, it’s still rich and satisfying.
Cheese swap: Using Gruyère or asiago instead of Parmesan gives a nuttier, more complex flavor that I’ve gotten rave reviews for.
Herbs: Sometimes I add thyme or sage alongside rosemary for extra herbal depth, especially in fall or winter.
Wine variations: For the pan sauce, I’ve experimented with Cabernet Sauvignon for a bolder sauce – just watch for bitterness and adjust seasoning accordingly.
Gluten-free: Replace seasoned breadcrumbs with gluten-free breadcrumbs or crushed nuts like almonds or pecans for texture.

How to Make Stuffed Beef Tenderloin with Mushroom Spinach Filling and Red Wine Pan Sauce Recipe

Step 1: Prepare the Mushroom Spinach Filling

Start by sautéing the chopped cremini mushrooms over medium heat, letting them release their moisture and start to brown — that’s where your flavor builds. Once the mushrooms have softened, toss in the finely chopped garlic and shallot, cooking until fragrant and translucent. Stir in the crushed red pepper flakes, kosher salt, and freshly ground black pepper to season. Add the baby spinach and cook just until wilted, then remove from heat to cool slightly. Mixing in softened butter, lemon zest, lemon juice, seasoned breadcrumbs, grated Parmesan, and fresh rosemary completes this rich, flavor-packed filling. The key is to get the mushrooms nicely caramelized which really amplifies the earthy taste.

Step 2: Prepare the Beef Tenderloin for Stuffing

Trim any silver skin and excess fat from the beef tenderloin to make it smooth and ready to butterfly. Now, this part can seem intimidating, but with a sharp knife, carefully slice the tenderloin horizontally through the center, leaving one side attached, so it opens like a book. Pat it dry inside and season generously with salt and pepper. Spread the mushroom spinach filling evenly over the inside, then gently roll it back up, tying with kitchen twine at 1.5-inch intervals to keep the shape secure. This rolling and tying keeps everything together, ensuring the filling won’t spill out during cooking.

Step 3: Sear and Roast the Beef

Heat a large oven-safe skillet over medium-high and sear the beef tenderloin on all sides until it develops a rich brown crust – about 2-3 minutes per side. This seals in the juices and creates flavor foundations for your pan sauce. Then transfer the skillet to a 425°F oven and roast the beef until it reaches your desired doneness (I recommend medium-rare at about 125°F internal temperature). Use a meat thermometer to check for precision – this is my favorite way to guarantee a perfectly cooked tenderloin every time. Once done, rest the beef tented loosely with foil for 15 minutes before slicing.

Step 4: Make the Red Wine Pan Sauce

While the beef rests, it’s time to make that luscious red wine pan sauce. Pour off any excess fat from the skillet but keep the browned bits stuck to the pan – that’s flavor gold! Place the skillet back on medium heat and add the chopped shallot, stirring until softened. Pour in the dry red wine, scraping up those delicious bits with a wooden spoon, and let it reduce by about half. Add the beef broth and continue reduction until the sauce thickens slightly. Finish by whisking in cold cubed butter one piece at a time for richness and shine. Taste and adjust seasoning with salt and pepper. This sauce is what’ll have your guests asking for seconds.

The image shows several slices of a rolled meat dish arranged in a curved line on a white plate. Each slice reveals three layers: the outer layer is a cooked brown meat with a slight sear, the middle layer is a thin light brown crust, and the inner layer is a green herb filling with a slightly coarse texture. Fresh green parsley leaves are placed around and under the slices as garnish. The plate rests on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Garnishes

I like to keep garnishes simple but elegant — a sprinkle of fresh rosemary or thyme over the sliced tenderloin adds a beautiful touch of color and aroma. Sometimes, I add a few lemon wedges on the side for an extra bright note. A drizzle of the red wine pan sauce right before serving really brings everything together.

Side Dishes

This stuffed beef tenderloin pairs wonderfully with creamy mashed potatoes or roasted baby carrots for a cozy feel. For something lighter, I’ve served it alongside garlic sautéed green beans or a fresh arugula salad with shaved parmesan and balsamic glaze. Whatever you choose, make sure the sides complement the rich flavors without overwhelming them.

Creative Ways to Present

For special occasions, I’ve sliced the stuffed tenderloin into thick medallions and arranged them artistically on a long platter with the red wine sauce drizzled on top and a sprinkle of chopped herbs. Adding roasted baby potatoes or colorful vegetables around the edges creates an inviting holiday centerpiece. Another fun idea is to serve individual servings on warm plates with fresh microgreens for a restaurant-quality touch.

Make Ahead and Storage

Storing Leftovers

If you have leftovers (which I hope you do because it reheats so well!), wrap the sliced beef tightly in foil or place it in an airtight container and refrigerate up to 3 days. I find that storing leftover pan sauce separately helps keep the meat from getting soggy.

Freezing

I’ve frozen both the cooked tenderloin slices and the pan sauce separately with good results. Just be sure to cool everything completely before freezing in freezer-safe containers. When thawed in the fridge overnight, both maintain their texture and flavor quite nicely.

Reheating

To reheat, I gently warm the beef slices in a low oven (around 275°F) covered loosely with foil to keep moisture, and heat the pan sauce in a small saucepan over medium-low heat. This method helps preserve tenderness without drying out. Avoid microwaving if you want to keep that juicy texture intact.

FAQs

Can I prepare the Stuffed Beef Tenderloin with Mushroom Spinach Filling and Red Wine Pan Sauce Recipe ahead of time?

Yes! You can prepare the tenderloin stuffed and tied the day before, then keep it covered in the fridge. This step helps deepen the flavors and makes the cooking day much easier. Just bring it to room temperature before searing and roasting.
What’s the best way to butterfly the beef tenderloin for stuffing?

Use a very sharp chef’s knife and slice horizontally down the length of the tenderloin, stopping about an inch from the edge so it opens like a book. This creates a broad surface for your stuffing but keeps it intact to roll back up.
How do I know when the beef tenderloin is perfectly cooked?

The best way is with an instant-read meat thermometer. For medium-rare, target 125°F internal temperature before resting. The temperature will rise slightly while resting to reach around 130-135°F.
Can I use a different type of meat for this recipe?

While this recipe shines with beef tenderloin, you can try similar stuffing techniques with pork loin or even a thick-cut chicken breast. Adjust cooking times accordingly, and note the flavors will vary.
What if I don’t have red wine for the pan sauce?

If you prefer not to use wine, you can substitute with additional beef broth mixed with a splash of balsamic vinegar to mimic acidity and depth, though the classic wine flavor is hard to beat.
