To cook St. Louis ribs in the oven, rub them, wrap them tight in foil, and bake at 300°F for about 2.5 hours for a half rack or 3 hours for a full rack, then unwrap, sauce, and finish 15 minutes uncovered. The ribs are done when the meat pulls back from the bone and a probe slides in with no resistance, which most pitmasters put around 195°F to 203°F inside.
Our St. Louis style ribs come from Heritage Duroc hogs, and the extra marbling is what keeps them juicy through a long, slow bake. Here is the method, a time chart, and the Super Bowl timing so the ribs land at kickoff.
What you need for St. Louis ribs in the oven
- 1 half rack (about 2 to 3 people) or 1 full rack (4 to 6 people) of St. Louis style ribs, thawed
- 1 tablespoon olive oil
- Dry rub: 2 tablespoons brown sugar, 1 tablespoon paprika, 2 teaspoons salt, 1 teaspoon black pepper, 1 teaspoon garlic powder
- 1/2 cup barbecue sauce, plus more for the table
- Heavy duty foil, a sheet pan, and a meat thermometer
Thaw the ribs in the fridge overnight, or two nights for a full rack. Take them out 30 minutes before they go in the oven.
How to cook St. Louis style ribs in the oven, step by step
- Heat the oven to 300°F. That is the temperature on our product page, and it is the sweet spot between slow and all afternoon.
- Pull the membrane. Flip the rack bone side up. Slide a butter knife under the thin skin at one end, grip it with a paper towel, and peel it off. It comes off in one sheet most of the time.
- Oil and rub. Coat the ribs with olive oil, then press the rub onto every side. Let them sit 15 minutes while the oven heats.
- Wrap tight. Lay the rack meat side up on a double sheet of foil, fold the foil over, and crimp every edge. The trapped steam is what makes them tender.
- Bake. Set the packet on a sheet pan. Half rack: about 2.5 hours. Full rack: about 3 hours. Do not open the foil to peek.
- Sauce and finish. Open the foil, brush on the sauce, and bake uncovered 15 minutes so it sets. For charred edges, broil 2 to 3 minutes and watch it the whole time.
- Rest and cut. Rest 10 minutes under loose foil, then cut between the bones.
Super Bowl timing for a 5:30 pm kickoff: ribs in the oven at 2:30, foil open at 5:00, sauce set by 5:15, rest, cut, done. The oven does all the work during the pregame.
St. Louis ribs oven time chart at 300°F
| Rack | Wrapped at 300°F | Unwrapped, sauced | Total |
|---|---|---|---|
| Half rack | 2 hours 15 minutes to 2 hours 30 minutes | 15 minutes | About 2 hours 45 minutes |
| Full rack | 2 hours 45 minutes to 3 hours | 15 minutes | About 3 hours 15 minutes |
| Two full racks | 3 hours, on two pans, swap shelves halfway | 15 minutes | About 3 hours 15 minutes |
Ovens vary, so start checking a half rack at 2 hours and a full rack at 2 hours 30 minutes. If you like ribs that fall off the bone, go to the long end of the range. If you like a little chew, pull them at the short end.
How to tell St. Louis ribs are done
Pork is safe at 145°F, per the USDA safe minimum temperature chart. Ribs are not tender at 145°F. The connective tissue keeps softening well past that, and the common pitmaster target is about 195°F to 203°F, which is why they need the long bake.
Three signs to check together: the meat has pulled back from the bone ends by a quarter inch or more, a thermometer probe slides between the bones like into warm butter, and when you lift the rack with tongs from one end it bends and the surface cracks.
Heritage Duroc ribs forgive a few extra minutes better than lean commodity ribs do, because there is more fat to keep them moist. For the grill and smoker versions, see our guide to how to BBQ heritage breed pork. The full line of cuts is in heritage pork fresh cuts.
Questions people ask about St. Louis ribs in the oven
How long should you cook St. Louis style ribs in the oven?
At 300°F wrapped in foil, about 2.5 hours for a half rack and 3 hours for a full rack, plus 15 minutes uncovered with sauce. Check for tenderness, not the clock.
Should I bake ribs at 275°F or 300°F?
Both work, and 275°F takes about 30 minutes longer for a slightly softer result. Our product page says 300°F for St. Louis ribs and 275°F for baby backs, which are leaner and cook faster.
What temperature should St. Louis ribs be done at?
Safe at 145°F per USDA. Tender is later, commonly quoted at 195°F to 203°F; use the bend test to confirm.
Do I bake ribs covered or uncovered?
Covered for the long bake, uncovered for the last 15 minutes with sauce. Foil traps steam and keeps the ribs from drying out.
Is 350°F too high for ribs?
Higher than we recommend. Our product page says 300°F, and hotter ovens push out moisture before the connective tissue softens. If you are short on time, buy a half rack, which finishes sooner.
Order the ribs, then set the oven. St. Louis ribs in the oven are the easiest ribs you will ever make, and they start with a rack worth the wait: Heritage Duroc, raised crate free with no antibiotics ever on Iowa family farms.
