Oven Baked 4-Ingredients Onion Soup Pork Loin

How to Make It

1. Preheat and Prepare

Preheat your oven to 350°F (175°C). Lightly grease a baking dish or roasting pan.

2. Layer the Onions

Spread the sliced onions evenly across the bottom of the dish. This creates a flavorful bed for the pork and prevents it from sticking.

3. Season the Pork

Place the pork loin on top of the onions. Sprinkle the onion soup mix evenly over the meat, making sure to coat the top well.

4. Add Liquid

Pour the broth (or water) around the pork—not directly over the top, so the seasoning stays in place. This liquid will combine with the soup mix and onion juices to form a rich sauce.

5. Bake Low and Slow

Cover the dish with foil and bake for about 1.5 to 2 hours, depending on the size of your pork loin. Halfway through, you can spoon some of the juices over the top to keep it moist.

6. Slice and Serve

Once the pork is fully cooked and tender, remove it from the oven. Let it rest for a few minutes, then slice into thick pieces. Spoon the onion gravy generously over each slice before serving.

Tips for the Best Results

• Don’t overcook: Pork loin is lean, so keeping it covered helps retain moisture.
• Use plenty of onions: They cook down significantly and are key to the flavor.
• Let it rest: This helps keep the juices inside the meat when slicing.

Serving Suggestions

This dish pairs beautifully with:

• Mashed potatoes (to soak up the onion gravy)
• Rice or egg noodles
• Roasted vegetables or green beans
