Contents
Equipment: Must-haves
- Crock Pot (slow cooker)
- Skillet (heavy-bottomed for searing)
- Cutting board
- Sharp knife
- Tongs
- Measuring spoon
- Mixing bowl
Equipment: Nice-to-haves
- Meat thermometer (for perfect doneness)
- Immersion blender (for super-smooth sauce)
- Gravy boat (for dramatic pouring)
Ingredients
- 1 pork tenderloin (about 1 to 1.25 lb)
- 8 oz mushroom, sliced (cremini or button)
- 1 small onion, thinly sliced
- 1 clove garlic, minced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 cup chicken broth
- 1/2 cup heavy cream
- 1 tablespoon Dijon mustard
- 1 teaspoon Worcestershire sauce
- 1 teaspoon dried thyme
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 teaspoons cornstarch
- 1 tablespoon water (for slurry)
- 1 tablespoon fresh parsley, chopped (for garnish)
Instructions
- Pat the pork tenderloin dry and season all over with salt and pepper.
- Heat the skillet over medium-high heat and add the olive oil until it shimmers.
- Sear the pork on all sides until nicely browned to lock in flavor, then transfer the pork to the Crock Pot.
- In the same skillet, lower the heat and add the butter so the pan gets cozy and buttery.
- Add the sliced onion and sauté until it softens and starts to caramelize slightly.
- Toss in the sliced mushroom and cook until the mushroom releases its liquid and starts to brown.
- Stir in the minced garlic and dried thyme, cooking just until fragrant so nobody gets bored.
- Pour the chicken broth into the skillet and scrape up the browned bits from the bottom with a spoon or spatula.
- Stir in the Dijon mustard and Worcestershire sauce, then let the mixture come to a gentle simmer for a minute.
- Transfer the mushroom-onion mixture into the Crock Pot around the pork so everything mingles nicely.
- Cover and cook on low until the pork is tender and cooked through; check with a meat thermometer if you want to be precise.
- When the pork reaches the correct temperature, remove it from the Crock Pot and tent it loosely with foil to rest.
- Mix the cornstarch and water in a small bowl to make a slurry so the sauce can thicken up and stop being shy.
- Stir the slurry into the sauce in the Crock Pot and let it cook uncovered on high until the sauce thickens and looks silky.
- If you prefer an ultra-smooth sauce, use the immersion blender directly in the Crock Pot for a few seconds; otherwise, leave it chunky and rustic.
- Slice the rested pork into medallions and nestle the slices back into the sauce to soak up the goodness.
- Spoon sauce over the pork on a plate, sprinkle with fresh parsley, and serve from a gravy boat if you want applause.
What Else You Should Know
Tip: Searing the pork first gives you flavor. Don’t skip it even if you’re tired — it’s worth five extra minutes.
Variation: Swap the heavy cream for half-and-half if you want a lighter finish, but the sauce will be a touch less rich. Make-ahead: Cook the pork a day early and store it in the fridge with the sauce.
Reheat gently so the cream doesn’t break. Thickening tip: If the sauce is too thin, stir in another tiny slurry of cornstarch and warm until glossy.
If it gets too thick, loosen with a splash of broth. Serving suggestion: Serve over mashed potato, egg noodle, or a mound of rice — the sauce wants a carbohydrate friend.
Diet swaps: For a dairy-free option, use coconut cream and skip the butter, though the flavor will shift toward tropical vibes. Doneness guide: Use the meat thermometer to aim for 145°F internal temperature, then let the pork rest so it finishes juicily.
Leftovers: Store refrigerated for up to three days. The sauce gets better after a night — like some people.
Final joke: If someone asks how you made this, just say it involved magic and a Crock Pot. They don’t need to know about the mustard.
