Balsamic pork loin crockpot dinners are about as easy as a weeknight gets. A lean loin can dry out fast in an oven, but the slow cooker keeps it in a bath of tangy glaze and gives you slices that cut clean and stay juicy.

A boneless pork loin cooks gently in balsamic vinegar, broth, garlic and herbs. The cooking liquid reduces into a glossy sauce for spooning over the slices.

Ingredients

3 lb boneless pork loin roast, fat cap trimmed to a thin layer
1 tsp kosher salt
1/2 tsp black pepper
1 Tbsp olive oil
1 medium yellow onion, cut into half-moons
5 cloves garlic, smashed
1/2 cup balsamic vinegar
1/2 cup low-sodium chicken broth
2 Tbsp brown sugar
1 Tbsp Dijon mustard
1 Tbsp soy sauce
2 tsp dried thyme
1 tsp dried rosemary, crushed
1 Tbsp cornstarch mixed with 2 Tbsp cold water

Directions

Pat the pork loin dry with paper towels. Rub it all over with the salt and pepper.
Heat the olive oil in a large skillet over medium-high heat. Sear the loin for 2 to 3 minutes per side until deep golden on all sides.
Scatter the onion and garlic across the bottom of a 6-quart slow cooker. Set the seared loin on top.
Whisk the balsamic vinegar, broth, brown sugar, Dijon, soy sauce, thyme and rosemary in a bowl. Pour it over and around the pork.
Cover and cook on LOW for 4 to 5 hours or on HIGH for 2 to 3 hours. Start checking at the early end of the range.
The pork is done when an instant-read thermometer in the thickest part reads 145°F. Do not wait for fork-tender, a loin turns dry past that point.
Move the loin to a cutting board and tent it with foil. Let it rest 10 minutes so the juices settle.
Pour the cooking liquid into a small saucepan and skim off any fat. Bring it to a simmer over medium heat.
Stir in the cornstarch slurry and cook 1 to 2 minutes until the sauce coats a spoon.
Slice the pork against the grain into 1/2-inch slices. Spoon the glaze over the top and serve.

Notes

Swap the brown sugar for honey if you like. Leftover slices keep 4 days in the fridge and freeze well in a little sauce. For a tangier sauce, add one more tablespoon of balsamic to the saucepan while it thickens. Serve over mashed potatoes, polenta or buttered noodles to catch every bit of glaze.

Why a slow cooker suits balsamic pork loin

Pork loin is lean, which is the whole problem. In a hot oven the outside overcooks before the center is ready. In a slow cooker the heat is gentle and wet, so the roast comes up to temperature without a dry ring around the edge. I have cooked loin every way, and the slow cooker version is the one that gets requested again. It also frees the oven for a tray of vegetables.

The vinegar does extra work here. Its acid softens the surface of the meat and the sugar in it cooks down into a glaze. Searing first adds the browned flavor that a slow cooker cannot make on its own.

Ingredient notes for the glaze and the roast

Pork loin: buy a center-cut boneless loin of about 3 pounds. It should be pale pink with a thin white fat cap. Skip anything labeled enhanced if you want to control the salt. If the roast comes tied with string, leave it on. It helps the loin keep an even shape so every slice cooks at the same rate.

Balsamic vinegar: a mid-priced bottle with grape must listed first tastes much better than a watery one. It will reduce, so the quality shows.

Garlic and onion: fresh is worth it. They melt into the liquid and give the sauce body. Fat and flavor sit in the sauce, so spoon it over each slice instead of leaving it in the pot.

Dijon mustard: a spoonful helps the sauce hold together and adds a gentle bite.

Cornstarch: it thickens the finished sauce in two minutes. Flour works but clouds the glaze.

Tips for juicy, sliceable pork

Use a thermometer: loin goes from perfect to chalky in under an hour. Pull it at 145°F, then rest it. The temperature will climb a few degrees as it sits. A cheap digital probe thermometer with an alarm is worth owning. Set it to 145°F and you can stop guessing.

Sear before you slow cook: the extra five minutes builds color and a deeper taste. Skipping it gives you pale, one-note pork. Pat the meat very dry before it hits the pan, or it steams instead of browning. Use a heavy skillet and do not crowd it.

Do not overcook, the most common mistake: people set loin for eight hours like a pot roast. Loin is not a tough cut. Four to five hours on LOW is plenty for a 3-pound roast.

Swaps and variations for balsamic pork

For a lighter sauce, use apple juice instead of brown sugar and skip the cornstarch. For heat, add a pinch of red pepper flakes. You can use pork tenderloin, but cut the time to 2 to 3 hours on LOW. A splash of orange juice also works with the balsamic. Garlic can be doubled if your family likes it strong.

Do not use a bone-in pork shoulder in this recipe. It needs much longer cooking and will turn out stringy instead of sliceable, which is great for pulled pork but wrong for this dish.

Serving balsamic pork loin at the table

Slice the loin at the table and pass the sauce in a small pitcher. Garlic mashed potatoes, roasted green beans and a simple arugula salad round it out. Crusty bread helps with any extra glaze. Set out a little extra sauce on the side, because people always ask for more.

Storing and reheating leftovers

Cool leftover slices and refrigerate them in the sauce for up to 4 days. The sauce keeps the meat from drying out. For longer storage, freeze slices in sauce for up to 3 months.

Thaw overnight in the fridge. Reheat gently in a covered skillet over low heat with a splash of broth. Avoid the microwave on high, it toughens thin slices.

Hi, I'm Iren Pavlenko. I read the top-ranked slow cooker recipes for a dish side by side and write down what they disagree on and what they all leave out — the cut, the pot size, and both the LOW and HIGH times. I write these guides so your weeknight dinner doesn't turn into a dry roast because a recipe never said which of those four things mattered.
