Equipment: Nice-to-haves

• Immersion blender (for a super-smooth sauce)
• Small bowl (for mixing slurry)
• Meat thermometer
• Serving platter

Ingredients

• 1 pork tenderloin (about 1–1.5 lb), trimmed
• 8 oz mushroom, sliced
• 1 small onion, thinly sliced
• 3 clove garlic, minced
• 1 tbsp olive oil
• 1 tbsp butter
• 1 tbsp flour (for light dredge)
• 1 tsp salt
• 1/2 tsp black pepper
• 1 tsp dried thyme
• 1 cup chicken broth
• 1 tbsp Dijon mustard
• 1/2 cup heavy cream
• 1 tsp cornstarch
• 1 tbsp cold water
• 1 tbsp fresh parsley, chopped (for garnish)

Instructions

1. Pat the pork tenderloin dry and season with salt, pepper, and dried thyme.
2. Lightly dredge the pork in flour, shaking off excess.
3. Heat the skillet over medium-high and add olive oil and butter until shimmering.
4. Sear the pork on all sides until nicely browned; then transfer the pork to the crock pot.
5. Add the sliced mushroom and onion to the same skillet and sauté until golden and fragrant.
6. Stir the garlic into the mushroom mixture and cook briefly until you can practically smell victory.
7. Pour the chicken broth into the skillet to deglaze, scraping up the browned bits with a spatula.
8. Whisk in the Dijon mustard, then bring the pan liquid to a simmer for a minute.
9. Pour the mushroom-broth mixture over the pork in the crock pot.
10. Cover and cook on low until the pork is cooked through and tender.
11. Remove the pork from the crock pot and tent it on a plate to rest.
12. Spoon the cooking liquid and mushrooms into the skillet and bring to a gentle simmer.
13. Stir the heavy cream into the pan liquid and reduce until slightly thickened.
14. Mix the cold water with cornstarch in a small bowl to make a slurry, then whisk it into the sauce to reach your desired thickness.
15. Taste the sauce and adjust seasoning with salt and pepper as needed.
16. Slice the rested pork tenderloin into medallions and spoon the mushroom cream sauce over the top.
17. Garnish with chopped parsley and serve while it’s warm and swoon-worthy.

What Else You Should Know

Timing tip: Cooking times vary by slow cooker. Use a meat thermometer to check for a safe internal temperature — and perfect tenderness.

Make-ahead: You can prepare the mushroom-onion mixture earlier and refrigerate it. Reheat before pouring over the pork so the crock pot doesn’t drop too much heat.

Thickening hack: If your sauce is too thin, mash a few mushroom bits or add a bit more cornstarch slurry. If it’s too thick, stir in a splash of broth.

Variation: Swap heavy cream for half-and-half for a lighter sauce, or add a splash of white wine to the deglaze step for extra depth. Serving suggestion: Serve with mashed potato, egg noodle, or a simple green vegetable to soak up the sauce.

That’s why carbs exist. Storage: Leftovers keep well in the fridge for a couple of days.

Reheat gently to avoid breaking the cream. Final chef-y thought: Searing really builds flavor, so don’t skip it unless you enjoy bland regrets.

This recipe is all about easy comfort with a touch of elegance — and a crock pot that thinks it’s a sous-chef.
