Ingredients

  • 2 Tbsp. shortening
  • 1 boneless pork roast (about 4 1/2 lb.)
  • 1 clove garlic, minced
  • 1 pkg. dry onion soup mix
  • 1/4 c. butter
  • 1 Tbsp. prepared mustard
  • 2 Tbsp. flour
  • 1 1/2 Tbsp. cracked black pepper
  • 1 Tbsp. brown sugar

Instructions

  1. Place the pork roast in a roasting pan.
  2. Sprinkle the roast lightly with minced garlic.
  3. Combine dry onion soup mix, butter, mustard, flour, black pepper, and brown sugar to form a paste.
  4. Spread the paste over the top, sides, and ends of the pork roast.
  5. Dot the top with shortening and cover the pan.
  6. Roast in a 475°F oven for 30 minutes.
  7. Reduce the oven temperature to 325°F and continue baking for about 1 1/2 to 2 hours, basting occasionally with drippings from the meat.
  8. When the roast is done or tender, carve or slice and serve.

Tips & Substitutions

For a deeper flavor, consider marinating the pork roast overnight with the garlic and some additional spices. If you don't have shortening, you can substitute with olive oil or butter. For a gluten-free option, use cornstarch instead of flour in the paste. Adjust the black pepper according to your spice preference, and feel free to add herbs like rosemary or thyme for extra aroma.

Serving Suggestions

This roast pairs beautifully with Cheddar Cheese Potato Salad and a side of Green Peas Supreme for a balanced meal. You can also serve it with crusty bread to soak up the flavorful drippings or alongside a fresh salad for a light contrast. Leftover pork can be used in sandwiches or as a filling for tacos.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover the pork with foil and warm it in a preheated oven at 325°F until heated through, about 15-20 minutes. For moist slices, consider adding a splash of broth to the container before reheating.

Frequently Asked Questions

Can I use a bone-in pork roast instead of a boneless one?

Yes, you can use a bone-in pork roast. Just adjust the cooking time as it may take longer to cook due to the bone. Ensure the internal temperature reaches at least 145°F for safe consumption.

What can I use instead of dry onion soup mix?

If you don’t have dry onion soup mix, you can make a homemade version by mixing together dehydrated onions, onion powder, garlic powder, and some salt. This will provide a similar flavor profile to your roast.

How do I know when the pork roast is done?

The best way to check if the pork roast is done is by using a meat thermometer. It should read 145°F in the thickest part of the meat. Let it rest for at least 10 minutes before carving to retain its juices.
