Ingredients
Servings: 4
-
2 to 2 1/2 pounds thick-cut pork slices (about 1-inch thick, bone-in or boneless)
-
1 can (20 ounces) pineapple slices in juice, undrained
-
1/3 cup packed brown sugar
-
1/4 cup soy sauce (regular or low-sodium)
-
1/3 cup ketchup
Ingredient Notes
Thick-cut pork slices: Look for pork shoulder slices or pork steak. These are cut from the shoulder and have good marbling. They are often less expensive than pork chops. The fat and connective tissue break down during long cooking, resulting in tender, juicy meat. Bone-in adds flavor. Boneless is easier to serve. Both work. Do not use thin-cut pork chops. They will dry out.
Canned pineapple slices in juice: Use a 20-ounce can of pineapple slices packed in juice, not syrup. The juice is essential for the sauce. Do not drain the can. You will use both the juice and the slices. If you cannot find slices, pineapple chunks or rings work fine.
Brown sugar: Pack the brown sugar firmly into the measuring cup. Light brown sugar provides mild, caramel-like sweetness. Dark brown sugar adds deeper, more molasses-forward flavor. Both work. Do not substitute white sugar.
Soy sauce: Use regular or low-sodium soy sauce. Low-sodium is preferred because the ketchup and brown sugar add plenty of flavor. If you use regular soy sauce, the dish may be saltier. Coconut aminos can be substituted for a gluten-free option.
Ketchup: Ketchup adds sweetness, tanginess, and a slight tomato flavor. It also helps thicken the sauce. Do not substitute tomato sauce or tomato paste, which have different consistencies and flavors.
Step-by-Step Instructions
Step 1: Arrange the Pork
Lay the raw thick-cut pork slices in a single layer on the bottom of a 4- to 6-quart slow cooker. It is fine if they overlap just a bit, but try to keep them mostly flat so they cook evenly. If necessary, cut larger slices in half to fit.
Step 2: Make the Sauce
In a medium bowl, whisk together the brown sugar, soy sauce, and ketchup. Whisk until the sugar is mostly dissolved and the sauce looks smooth and glossy. The mixture will be thick.
Step 3: Add the Pineapple Juice
Open the can of pineapple. Pour all of the pineapple juice from the can into the brown sugar mixture. Whisk to combine. The sauce will thin out significantly. Set the pineapple slices aside for now.
Step 4: Add the Sauce
Pour the sauce mixture evenly over the pork slices in the slow cooker. Make sure each piece is coated with some of the liquid. Use a spoon or spatula to spread the sauce around if needed. Do not stir.
Step 5: Add the Pineapple Slices
Arrange the pineapple slices on top of the pork. Tuck them in so each piece of meat has a bit of pineapple flavor over it. Any extra slices can be nestled between the pieces of pork. The pineapple will soften and infuse the sauce with its flavor.
Step 6: Slow Cook
Cover the slow cooker with the lid. Cook on LOW for 6 to 7 hours, or on HIGH for 3 to 4 hours. The pork is ready when it is very tender and reaches at least 145°F (63°C) in the thickest part when checked with a meat thermometer. The meat should pull apart easily with a fork.
Step 7: Skim and Serve
Once done, taste the sauce. If you like, skim off any excess fat from the surface with a spoon. The pork slices can be served as they are, or you can gently transfer them and the pineapple to a platter and spoon some of the sauce over the top.
Serve the pineapple pork slices hot with extra sauce spooned over each serving.
How to Serve Pineapple Pork Slices
This sweet and savory pork pairs beautifully with a variety of sides.
Over Rice: White rice or jasmine rice absorbs the sweet-savory sauce perfectly.
With Mashed Potatoes: Creamy mashed potatoes balance the sweetness of the pineapple.
With Roasted Vegetables: Roasted green beans, broccoli, or asparagus add color and balance.
With Steamed Rice and Broccoli: A classic pairing. The broccoli adds freshness and crunch.
With Noodles: Wide egg noodles or lo mein noodles catch the sauce beautifully.
With a Simple Green Salad: A tangy vinaigrette cuts through the richness.
Variations & Tips
Make It Spicier: Add 1/2 teaspoon of red pepper flakes or 1 tablespoon of sriracha to the sauce mixture.
Make It With Ginger: Add 1 teaspoon of ground ginger or 1 tablespoon of finely grated fresh ginger to the sauce.
Make It With Garlic: Add 4 to 5 cloves of minced garlic to the sauce mixture.
Make It With Bell Peppers: Add 1 sliced bell pepper to the slow cooker along with the pineapple.
Make It With Onion: Add 1 large sliced onion to the bottom of the slow cooker before adding the pork.
Make It With Pineapple Chunks: Substitute pineapple chunks for the slices. The chunks are easier to serve alongside the pork.
Make It in the Oven: Preheat oven to 325°F (163°C). Place pork in a 9×13-inch baking dish. Mix sauce ingredients and pour over pork. Arrange pineapple on top. Cover tightly with foil and bake for 1 1/2 to 2 hours until tender.
Make It on the Stove: Brown pork slices in a large pot. Add sauce and pineapple. Simmer over low heat for 45 to 60 minutes until tender.
Pro Tips for Absolute Success
Use thick-cut pork slices. Thin slices will dry out during long cooking. Look for slices that are at least 1 inch thick.
Do not drain the pineapple. The juice is essential for the sauce. Pour the entire can into the sauce mixture.
Do not add extra liquid. The pineapple juice and the juices from the pork provide enough moisture. Adding more liquid will thin the sauce.
Arrange the pineapple on top. The pineapple does not need to be submerged. It will soften and release flavor as it sits on top of the pork.
Cook until very tender. Pork slices need time for the connective tissue to break down. Do not rush. The meat should pull apart easily with a fork.
Skim the fat before serving. Pork slices can release a significant amount of fat. A quick skim with a spoon makes the sauce cleaner and more flavorful.
Frequently Asked Questions
Can I use pork chops instead of pork slices?
Yes, but choose thick-cut chops. Thin chops will dry out. Bone-in chops add more flavor. Reduce the cook time slightly and check for tenderness early.
Can I use fresh pineapple instead of canned?
Yes. Use about 2 cups of fresh pineapple chunks or slices. Add 1/2 cup of pineapple juice or water to the sauce to replace the liquid from the can.
Can I use a different meat?
Yes. This sauce works beautifully with chicken thighs or pork shoulder. Adjust cook times accordingly. Chicken thighs take 4 to 5 hours on LOW.
Can I cook this on high instead of low?
Yes. Cook on HIGH for 3 to 4 hours. However, LOW is strongly preferred. The gentler heat keeps the pork more moist and allows the flavors to meld more thoroughly.
My sauce is too thin. What do I do?
Remove the pork and pineapple. Pour the sauce into a small saucepan. Simmer over medium heat for 10 to 15 minutes until reduced and thickened. Pour back over the pork.
My sauce is too thick. What do I do?
Stir in warm water or pineapple juice, one tablespoon at a time, until it reaches your desired consistency.
Can I double this recipe?
Only if your slow cooker is at least 7 quarts. Do not fill more than two-thirds full. If doubling, you may need to layer the pork. Add 30 to 60 minutes to the cook time.
Can I freeze the leftovers?
Yes. Place the pork and sauce in an airtight container. Freeze for up to 3 months. Thaw overnight in the refrigerator. Reheat gently on the stovetop or in the microwave.
Why is my pork tough?
It did not cook long enough. Pork slices need time for the connective tissue to break down. Continue cooking on LOW and check every 30 minutes until the meat pulls apart easily with a fork.
Can I add vegetables to the slow cooker?
Yes. Add sliced bell peppers, onions, or carrots during the last 2 hours of cooking. Add them too early and they will become mushy.
The Vintage Appeal
There was a time when pineapple and pork were a glamorous combination. Think of the 1950s and 1960s. Pineapple upside-down cakes. Glazed hams studded with pineapple rings. Sweet-and-sour meatballs served at cocktail parties. It was a flavor profile that said celebration.
This recipe captures that mid-century charm. It is sweet without being cloying. It is savory without being heavy. The pineapple adds a bright, tropical note. The brown sugar adds depth. The soy sauce and ketchup create a complex, tangy glaze that is far more than the sum of its parts.
But this is not just a nostalgia trip. This is genuinely good food. The slow cooker transforms inexpensive pork slices into something tender and luxurious. The sauce thickens into a glossy, clinging glaze. The pineapple softens and melts into the background.
This is the kind of recipe that deserves a place on your table, not because it is vintage, but because it is delicious. Try it once. You will understand why it survived.
