Grilled Filet Mignon with Porcini Bordelaise

Grilled Filet Mignon with Porcini Bordelaise

Steak night should taste rich, cozy, and worth the little extra effort. Grilled Filet Mignon with Porcini Bordelaise brings tender beef, creamy mashed potatoes, garlicky spinach, and a glossy sherry mushroom sauce onto one plate.

This is a full steak dinner built from simple pieces: seared filet mignon, buttery Yukon Gold potatoes, quick spinach, and a porcini sherry bordelaise that makes the whole dish feel restaurant style. It fits beautifully into a hearty BEEF meal when you want something more special than a regular weeknight steak.

The timing is still manageable because the potatoes boil while the sauce reduces, and the spinach takes only a few minutes at the end. I like to start the porcini soaking before I touch the potatoes so the mushroom liquid is ready when the shallots hit the pan.

Serve it for date night, a birthday dinner, or a quiet weekend DINNER when you want the plate to feel complete without making three complicated recipes.

You can keep the filet medium rare, cook it closer to medium, or make the sides ahead so the final sear feels relaxed. It is rich enough for steak lovers but balanced with spinach and a silky sauce instead of anything too heavy.

Why You’ll Love This Grilled Filet Mignon with Porcini Bordelaise:

• Tender steak: Filet mignon cooks quickly and stays buttery when rested before slicing.
• Creamy base: Yukon Gold potatoes mash into a smooth, rich bed for catching the sauce.
• Deep sauce: Porcini mushrooms, sherry, beef stock, and thyme reduce into a savory bordelaise.
• Balanced plate: Spinach adds freshness beside the steak and potatoes.
• Special feel: The whole meal looks polished but uses straightforward steps.

Ingredients You’ll Need:

Here is what you need for a full steakhouse style plate at home.

For the Filet Mignon:

• Filet mignon steaks: 2 steaks, 6 to 8 oz each, thick cut so they sear well and stay tender.
• Olive oil: 2 tablespoons helps the steaks brown over high heat.
• Butter: 2 tablespoons for basting with garlic and thyme.
• Garlic cloves: 3 smashed cloves add savory flavor to the butter.
• Fresh thyme: 2 sprigs give the steak a warm herbal finish.
• Salt: to taste, season generously before cooking.
• Black pepper: to taste, adds a simple steakhouse bite.

Mashed Potatoes:

• Yukon Gold potatoes: 4 peeled and cubed potatoes mash creamy without turning gluey.
• Butter: 4 tablespoons make the potatoes rich and smooth.
• Heavy cream: ½ cup warms into the potatoes for a silky texture.
• Salt: to taste, brings out the buttery potato flavor.
• Black pepper: to taste, adds gentle warmth.

Sautéed Spinach:

• Fresh spinach: 4 cups wilt down quickly into a tender green layer.
• Garlic: 2 cloves minced for a quick savory base.
• Olive oil: 1 tablespoon helps the garlic bloom without burning.

Porcini Sherry Bordelaise:

• Dried porcini mushrooms: 1 oz adds deep earthy flavor to the sauce.
• Shallot: 1 minced shallot softens into the butter and gives the sauce a sweet savory start.
• Butter: 1 tablespoon for sautéing, plus a small extra knob if you want a glossy finish.
• Dry sherry: ½ cup gives the sauce nutty depth and gentle acidity.
• Beef stock: 1 cup forms the body of the bordelaise.
• Worcestershire sauce: 1 teaspoon adds rich, salty depth.
• Fresh thyme: 1 teaspoon adds a clean herbal note.

Step by Step Instructions:

1. Soak the mushrooms: Place the dried porcini mushrooms in a small bowl and cover with warm water for 10 minutes. Lift them out, chop them if large, and save a few tablespoons of soaking liquid if it is not gritty.
2. Cook the potatoes: Add the cubed Yukon Gold potatoes to a pot of salted water and boil until fork tender, about 15 to 18 minutes. Drain well, then mash with butter, warm heavy cream, salt, and black pepper until smooth.
3. Make the bordelaise: Melt butter in a small saucepan over medium heat, then cook the shallot for 2 to 3 minutes until softened. Add the porcini, sherry, beef stock, Worcestershire sauce, thyme, and a splash of the clean porcini soaking liquid, then simmer until reduced by half and glossy.
4. Grill the steaks: Pat the filet mignon dry and season well with salt and black pepper. Grill or sear over high heat for 3 to 4 minutes per side for medium rare, then add butter, smashed garlic, and thyme during the final minute and baste the steaks.
5. Wilt the spinach: Warm olive oil in a skillet over medium heat, add the minced garlic, and stir for about 30 seconds. Add the spinach and cook just until wilted, tossing often so it stays bright.
6. Rest and plate: Let the steaks rest for 5 minutes so the juices settle. Spoon mashed potatoes onto plates, add spinach, set the filet on top, and finish with the porcini sherry bordelaise.

Recipe Tips:

• Dry the steak: Patting the filet dry before seasoning helps it sear instead of steaming.
• Reduce fully: Let the bordelaise simmer until it looks slightly syrupy, or it will taste thin on the plate.
• Avoid cold cream: Warm the heavy cream before mashing so the potatoes stay smooth and hot.
• Rest the beef: Cutting too soon lets the juices run out and makes the filet less tender.

Variations and Customization Ideas:

• Protein swap: Use ribeye, New York strip, or beef tenderloin medallions with the same sauce.
• Spice touch: Add cracked peppercorns to the bordelaise for a sharper steakhouse flavor.
• Dietary option: Use lactose free cream and butter alternatives for the potatoes if needed.
• Budget move: Try sirloin medallions and keep the porcini sauce for big flavor.
• Vegetable change: Swap spinach for broccolini, asparagus, or garlicky green beans.

Serving Suggestions:

• Crisp salad: A lemon dressed green salad cuts through the richness of the steak and potatoes.
• Roasted mushrooms: Extra mushrooms make the porcini sauce feel even deeper and cozier.
• Warm bread: Crusty bread is perfect for catching the bordelaise around the plate.
• Steak pairing: For another beef dinner with bold sauce flavor, try Cajun Steak Tips with Parmesan Penne.
• Simple dessert: Finish with berries and whipped cream to keep the meal from feeling too heavy.

How to Store and Reheat:

Store leftover steak, potatoes, spinach, and sauce in separate airtight containers in the refrigerator for up to 3 days. Do not leave the cooked steak or sides at room temperature for more than 2 hours.

Freezing is best for the sauce only, since mashed potatoes can turn watery and filet mignon may lose tenderness after thawing. Freeze the bordelaise in a small airtight container for up to 2 months.

Reheat the steak gently in a covered skillet over low heat with a splash of beef stock or sauce. Warm the mashed potatoes with a little cream, reheat the spinach quickly, and bring leftovers to 165°F before serving.

Recipe FAQ’s:

How do I know when filet mignon is medium rare?

Use an instant read thermometer and pull the steak around 130°F, then let it rest. The temperature will rise a few degrees as it sits, giving you a warm pink center.

Can I make porcini bordelaise ahead of time?

Yes, the sauce can be made 1 day ahead and stored in the refrigerator. Reheat it gently over low heat and whisk in a small pat of butter right before serving.

What can I use instead of dry sherry?

Use a dry red wine or a splash of beef stock with a little balsamic vinegar for balance. The flavor will change slightly, but the sauce will still be savory and rich.

Grilled Filet Mignon with Porcini Bordelaise works because every layer has a job: creamy potatoes, bright spinach, tender steak, and a deep mushroom sauce that ties it all together. It feels special without needing a long restaurant style prep list.

For another steak dinner with a tangy finish, save Balsamic Flank Steak with Blue Cheese for later.
