Classic Demi Glace Pork Tenderloin with Green Beans and Mashed Potatoes

Classic Demi-Glace Pork Tenderloin with Green Beans and Mashed Potatoes: A Weeknight Meal with Restaurant Flavor

There’s something deeply comforting about a plate of pork tenderloin with mashed potatoes and green beans. It’s a timeless trio that feels familiar and satisfying. But when you bring in Le Sauce & Co.’s Classic Demi-Glace Gourmet Sauce, that classic dinner gets a major upgrade—without adding hours to your cooking routine.

This is how you bring restaurant-quality flavor to your home kitchen with minimal effort. Whether you're cooking for someone special or just want to treat yourself, this meal is both elevated and accessible.

The Star of the Plate: Pork Tenderloin

Pork tenderloin is one of the most underrated proteins. It’s lean, flavorful, and cooks quickly—ideal for weeknight meals. A simple seasoning of salt, pepper, garlic powder, and a touch of paprika gives it a beautiful golden crust when seared.

Start by searing the tenderloin in a hot skillet until it’s browned on all sides. Then transfer it to the oven at 400°F for about 15–18 minutes, or until the internal temperature reaches 145°F. Rest it before slicing to keep all those natural juices inside.

The Secret Weapon: Classic Demi-Glace

The real game-changer here is Le Sauce & Co.’s Classic Demi-Glace. Traditionally, demi-glace is a French sauce that takes hours to reduce and perfect. But this version skips the time and hassle while keeping all the richness and depth.

Once your pork is sliced, just heat the pouch of demi-glace and spoon it generously over the top. It clings beautifully to the meat and brings a deep, velvety finish with notes of roasted beef stock, wine, and herbs. It’s rich without being overpowering—and it turns your home-cooked dinner into something that tastes like it came from a bistro kitchen.

The Sides: Creamy Mashed Potatoes and Green Beans

Mashed potatoes are the perfect partner for demi-glace. Their creamy texture soaks up the sauce like a dream. A simple mash made with Yukon gold potatoes, butter, and a splash of milk or cream is all you need. No frills—just buttery, pillowy comfort.

Green beans balance the plate with freshness and crunch. Steam or blanch them until tender-crisp, then toss with a little olive oil, lemon zest, and salt. They bring brightness to each bite and round out the meal beautifully.

A Dinner That Feels Like a Treat

What makes this dish so special isn’t that it’s complicated—it’s that each component is thoughtfully prepared and comes together effortlessly. With Le Sauce & Co.’s Classic Demi-Glace doing the heavy lifting, you don’t need to spend hours in the kitchen to make something truly memorable.

Whether it’s a quiet Tuesday evening or a Friday night at home, this meal feels like a celebration. It’s what happens when comfort food meets gourmet flavor—and you realize that with just a little help, dinner can be easy, elegant, and completely satisfying.
