Crockpot Pork Roast with a Crispy Golden Crust

Why this recipe works

Pork shoulder is full of fat and connective tissue, which is exactly what you want for a long cook. Over 8 hours that collagen melts into the meat, so the roast stays juicy even if dinner runs an hour late. Lean cuts can't do that.

The roast sits on a bed of thick onion slices with only 1 cup of liquid. The onions lift the meat out of the broth so it roasts more than it boils, and the pork releases plenty of its own juice as it cooks.

The last step is the detail that matters. Slow cookers trap steam, so the fat cap comes out pale and soft. Pat it dry, slide the roast under the broiler for 3 to 5 minutes, and the top turns golden with crisp edges.

Ingredient notes

Pork shoulder: Look for boneless pork shoulder, also sold as Boston butt, 3 1/2 to 4 lb, with the fat cap left on. If it comes in netting or twine, leave that on so it holds its shape for slicing. Bone-in works too; add about 1 hour on LOW.

The rub: Kosher salt, pepper, garlic powder, onion powder, smoked paprika, dried thyme and a little brown sugar. The sugar helps the top brown under the broiler. If you use fine table salt, cut the amount to 1 1/4 tsp.

Broth: Low-sodium chicken broth keeps the gravy from getting too salty, since the juices concentrate. Apple cider vinegar and Worcestershire sauce add the tang and depth that pork drippings need.

Onion and garlic: One large yellow onion cut into thick rounds, plus smashed garlic cloves. They soften into the juices and go straight into the gravy.

Cornstarch: Mixed with cold water, it thickens the strained juices in about 2 minutes on the stove.

How to make crockpot pork roast

Start with a fully thawed roast. Pat it dry, score the fat cap in a shallow crosshatch, and rub the spice mix over every side. Scoring lets the seasoning reach the meat and helps the fat render and crisp later.

Layer the onion and garlic in a 6-quart slow cooker, pour in the broth, vinegar and Worcestershire, and set the pork on top with the fat side up. As the fat melts it bastes the meat. Cover and cook on LOW for 8 to 9 hours or HIGH for 4 to 5 hours, and keep the lid on, because each peek costs about 20 minutes of heat.

Pork is safe to eat at 145°F, but a shoulder is still tough at that point. For slices that hold together yet cut with a fork, take it to 185 to 195°F in the thickest part. If you'd rather shred it, keep going to 200 to 205°F.

Lift the roast onto a foil-lined sheet pan, pat the top dry with paper towels, and broil about 6 inches from the element until the top is deep golden and the edges crisp, 3 to 5 minutes. Rest it 10 minutes, then slice across the grain into 1/2-inch pieces. While it rests, skim the fat from the juices and simmer them with the cornstarch slurry until the gravy turns glossy.

Common mistakes (and how to fix them)

The pork is tough and hard to slice. It isn't done yet. Shoulder gets tender only after the collagen breaks down, so cover it and give it another 45 to 60 minutes, then check the temperature again.

The pork is dry. This usually means a lean cut such as pork loin was cooked on a shoulder schedule. Loin needs far less time (see the substitutions). With shoulder, dryness is rare; spoon warm juices over the slices.

The top won't crisp. The surface was still wet. Blot it well before broiling, and move the rack one level closer if nothing happens after 3 minutes. Stay by the oven, since brown sugar goes from golden to burnt in under a minute.

The gravy is thin or greasy. Skim the fat first with a spoon or a fat separator, then simmer with the slurry at a real bubble. Cornstarch doesn't thicken until it boils. Still thin? Stir in 1 more tsp of cornstarch mixed with 1 tsp of water.

The juices taste flat. Add a splash of cider vinegar and a pinch of salt at the end.

What to serve with crockpot pork roast

Mashed potatoes are the natural choice, because they hold the onion gravy. Buttered egg noodles or steamed white rice do the same job with less work.

For something green, try roasted green beans or steamed broccoli with lemon. A vinegar-based coleslaw or unsweetened applesauce on the side cuts through the richness of the pork. Leftover slices make good sandwiches on toasted rolls with a spoonful of gravy.
