Equipment: Must-haves

• Slow cooker
• Skillet (heavy-bottomed)
• Cutting board
• Sharp knife
• Tongs
• Meat thermometer
• Pot for cooking pasta
• Colander
• Measuring cups and spoons
• Mixing bowl
• Whisk
• Wooden spoon

Equipment: Nice-to-haves

• Immersion blender (for silky sauce)
• Kitchen twine (to keep pork neat)
• Fine-mesh strainer
• Pastry brush (for fun)

Ingredients

• 1 pork loin (about 2 pounds), trimmed of excess fat
• 1 tablespoon olive oil
• 1 teaspoon salt, plus more to taste
• 1/2 teaspoon black pepper, plus more to taste
• 1 clove garlic, minced
• 1 small onion, thinly sliced
• 2 tablespoons butter
• 1 cup heavy cream
• 1/2 cup chicken broth
• 1 cup grated Parmesan cheese, plus extra for serving
• 1 teaspoon Dijon mustard
• 1/2 teaspoon dried thyme
• 1 tablespoon cornstarch
• 2 tablespoons water (for slurry)
• 8 ounces fettuccine (or pasta of your choice)
• 1 tablespoon chopped parsley, for garnish
• 1 teaspoon lemon juice (optional, for brightness)

Instructions

1. Pat the pork loin dry and season it with salt and pepper on all sides.
2. Heat the skillet over medium-high and add the olive oil until shimmering.
3. Sear the pork loin on all sides until it develops a golden crust; use tongs to roll and brown evenly.
4. Transfer the pork loin to the slow cooker and tuck the onion and garlic around it.
5. Drop the butter into the slow cooker, then pour in the chicken broth and heavy cream and stir in the Dijon and thyme.
6. Cover and cook on low until the pork registers safe on a meat thermometer and is tender; check doneness and don’t guess.
7. When the pork is done, transfer it to the cutting board and tent it loosely to rest while you make the sauce.
8. Skim any excess fat from the surface of the slow cooker liquid, then strain the liquid into a mixing bowl or pour it into the skillet to finish on the stove.
9. Bring the sauce to a gentle simmer and whisk together the cornstarch with the water to make a slurry.
10. Whisk the slurry into the simmering sauce and cook until the sauce thickens and coats the back of a spoon.
11. Reduce heat and stir in the Parmesan until it melts into a smooth, creamy sauce, finishing with a splash of lemon juice if you like bright notes.
12. Meanwhile, cook the fettuccine in a pot of salted boiling water until al dente and drain in the colander.
13. Toss the drained pasta with a ladle of the Alfredo sauce to coat the noodles and transfer to serving plates.
14. Slice the rested pork loin into medallions and arrange them on top of the sauced pasta.
15. Spoon more sauce over the pork, sprinkle with parsley and extra Parmesan, and serve immediately.

Good to Know

Tips: Patting the pork dry before searing is the secret to a pretty crust; dry skin becomes golden skin and everyone applauds.\n\nTiming: Slow cooker times vary; low is gentle and forgiving. Use a meat thermometer and pull the pork at the right internal temperature for the juiciest result.\n\nSauce tricks: If you want an ultra-silky sauce, use an immersion blender for a few seconds after adding the Parmesan.

For a thicker sauce, let it simmer a touch longer or add a pinch more cornstarch slurry.\n\nVariations: Swap the dried thyme for rosemary or a pinch of nutmeg for a subtle cozy twist. Stir in sautéed mushroom slices for an earthy upgrade.\n\nServing suggestions: Plate the pork and sauce over pasta, mashed potato, or steamed vegetable for a lighter option.

A crisp green salad and crusty bread are excellent sidekicks.\n\nMake-ahead and storage: The pork and sauce keep well in the fridge for several days. Reheat gently on the stove and add a splash of broth or cream if the sauce tightens up.\n\nPro tip: A squeeze of lemon just before serving brightens the Alfredo and makes people say, “Hmm, did you go to culinary school?” even if you learned from YouTube and optimism.
