These oven-baked St. Louis style pork ribs are some of the best barbecue ribs you’ll ever taste. Cooked low and slow, they have a delicious, crisp crust, a juicy, tender center, and sweet, spicy, tangy barbecue flavor in every bite. With no grill and no smoker required, they’re easy enough for beginners and deliver competition-worthy results every time. I like to prepare several racks for game days and summer cookouts and never have any leftovers!
What Are St. Louis Style Ribs?
St. Louis ribs differ from baby back ribs in cut, texture, and taste. St. Louis ribs are a trimmed version of spare ribs, which come from the lower portion of the ribcage, near the pig’s belly. Meanwhile, baby back ribs are cut from the upper portion of the ribcage near the loin. As a result, St. Louis ribs have much more fat, which breaks down as the meat cooks, creating an incredibly juicy texture.
Because they’re cut from the wider section of the ribs, St. Louis ribs are larger and meatier than baby back ribs, which are shorter with a curved shape. As a result of these differences, St. Louis style ribs are typically easier to prepare and are ideal for low and slow cooking methods that break down connective tissue, resulting in tender ribs that practically melt in your mouth with each bite.
Ingredients and Notes
See the recipe card below for the complete ingredient list and instructions.
- Ribs – I use two racks of St. Louis pork ribs, roughly two and a half to three pounds (one point one to one point three kilograms) in weight.
- Yellow Mustard – Similar to its use in beef Wellington recipes, mustard acts as a binder, helping the seasonings cling to the meat. You won’t taste it in the finished dish, but you can omit it if you really aren’t a mustard fan.
- Dry Rub – I use a combination of kosher salt, brown sugar, smoked paprika, garlic powder, onion powder, black pepper, chili powder, and cayenne to create a nice crust and give the ribs a sweet, savory, smoky flavor with just a hint of spice.
- Apple Juice – This helps create steam, tenderizing the meat and infusing it with a sweet taste.
- Butter – Melted butter enriches the ribs as they cook, creating an incredibly juicy texture and richer flavor.
- Brown Sugar – I use either light or dark brown sugar to enhance the caramelization process and add a subtle sweetness that balances the spices in the seasoning rub and sauce.
- Apple Cider Vinegar – The acidity tenderizes the pork and cuts through some of the richness, adding a subtle tangy taste.
- BBQ Sauce – You can use any store-bought barbecue sauce you like best. However, I prefer to make my own, combining ketchup, chicken stock, brown sugar, molasses, apple cider vinegar, Worcestershire sauce, mustard, and spices for a sweet, smoky, tangy glaze that perfectly complements the ribs.

Nick’s Tips for Success
- Season generously. Ribs can handle a lot of flavor, so make sure the dry rub evenly coats every surface.
- Let the rub sit. Allowing the ribs to rest for at least 30 minutes (or overnight in the refrigerator) gives the seasonings time to penetrate the meat.
- Cook low and slow. Resist the urge to increase the oven temperature. Low heat is the key to tender, juicy ribs.
- Seal the foil tightly. During the wrap phase, make sure the foil is completely sealed to trap steam and lock in moisture. If there are gaps in the foil, steam will escape, and the ribs are likely to become tough and dry.
- Save the drippings. Adding the rib drippings to the BBQ sauce creates deeper flavor and gives the sauce a rich, authentic barbecue taste that takes the ribs from good to great.
- Don’t overcook. Contrary to popular belief, fall-off-the-bone ribs are actually overcooked. For the best results, bake just until the ribs are tender with a slight bite and the meat is easy to remove from the bones. You’ll know they’re done when the thickest part of your ribs reaches an internal temperature of 200°F to 203°F (93°C to 95°C) when measured with a meat thermometer. Adjust the cook time as needed, depending on your oven and the size of your ribs.
- Cut clean portions. To serve, flip the rack bone-side up and use a sharp knife to slice between each bone to separate the individual ribs.

- Place the ribs meat-side up on a wire rack set over a large sheet tray.
- Bake for two and a half to three hours, or until the ribs are tender but not falling apart. The meat should have pulled back from the bones by about ½ inch (one centimeter).

Notes
- For the best flavor, season the ribs and refrigerate them uncovered overnight before cooking.
- St. Louis-style ribs are done when they are tender with a slight bite and reach an internal temperature of 200-203°F (93-95°C).
– Refrigerator: Transfer cooled ribs to an airtight container, and store them in the refrigerator for up to four days.
– Freezer: Freeze cooled ribs for up to three months. Wrap individual portions or whole racks tightly in plastic wrap and aluminum foil, then place them in a freezer-safe container or zip-top bag.
– Reheating: Reheat ribs covered with foil in a 300°F (150°C) oven for 20-30 minutes if thawed or 45-60 minutes from frozen, until heated through. For the best texture, brush with a little extra barbecue sauce before reheating. Avoid microwaving when possible, as it can dry out the meat and soften the bark.

These ribs pair well with classic barbecue sides like coleslaw, baked beans, mac and cheese, potato salad, cornbread, grilled corn, or a simple green salad.
Yes. Prepare the ribs as directed, and cook them over indirect heat at about 275°F to 300°F (135°C to 150°C). Then, finish them over direct heat for a few minutes to create a caramelized crust.
I don’t recommend it. The membrane becomes tough as it cooks, tasting like a thin layer of plastic on the ribs. It can also prevent the seasoning from penetrating the ribs, negatively impacting their flavor.
