These oven baked St. Louis style ribs are my go-to when I want serious BBQ flavor without firing up a grill.
Low and slow in foil, then a hot finish with sauce — the result is fall-off-the-bone tender meat with a sticky, caramelized crust every single time.
No special equipment needed, just a baking sheet and foil.
The dry rub takes 5 minutes to mix and most of the cook time is completely hands-off.
Serve with my favorite Perfect Boiled Corn On The Cob or Oven Fries.
For a summer potluck, you can pair them with this flavorful Mango Salsa.

Why You’ll Love This Recipe
- St. Louis ribs have more fat than baby backs, which means they stay juicy through the full 2-hour bake — no babysitting required
- The foil seal traps steam and breaks down the collagen, giving you fall-off-the-bone texture without a smoker or grill
- One dry rub, one sauce, done — easy cleanup and big flavor
What Are St. Louis Style Ribs?
St. Louis-style ribs come from the belly side of the rib cage and are trimmed into a neat, rectangular rack.
They are meatier and more flavorful than baby back ribs, with a little more fat that keeps them juicy when cooked slowly.
The name “St. Louis style” refers to the cut, not the seasoning or sauce.
These ribs are a barbecue competition classic.
I always cook St. Louis style ribs at home and order baby back when I’m at a restaurant.
St. Louis have more fat, which means more flavor and a more forgiving cook — much harder to dry out.
They’re also usually less expensive than baby backs, which matters when you’re feeding a family.
Ingredients for Baked Saint Louis Ribs
Here’s what you need for the best St. Louis ribs in the oven (see recipe card for full quantities):
• St. Louis ribs, about 3 to 4 pounds
• Barbecue sauce, your favorite kind
• Dry rub: paprika, garlic powder, cayenne, oregano, salt, black pepper, and a touch of brown sugar
How To Make Oven Baked St Louis Ribs
- The method has three stages: season, bake covered, then finish with sauce.
- You’ll season the ribs with the dry rub and let them rest while the oven preheats.
- Then they go in tightly wrapped in foil for 2 hours — this is where the real tenderizing happens.
- The last 20–25 minutes are uncovered with BBQ sauce, which gives you that sticky, caramelized crust.
- The one thing that matters most: don’t rush the foil stage.
- Two full hours at 350°F is what breaks down the collagen and gives you meat that pulls cleanly from the bone.
- Check the full step-by-step with photos in the recipe card below.
Recipe Tips
- Choose ribs with even marbling and no dry edges
- The foil isn’t optional — it traps the steam that breaks down the collagen in the meat. Skip it and you’ll have tough, dry ribs instead of tender ones.
- Use a meat thermometer — ribs are done at 190–205°F (88–96°C) Let rest 5–10 minutes before cutting
- Pair a spicy rub with a sweet sauce for the best flavor balance
Grill Option
If you want a charred, grilled finish: complete the full oven method through the foil bake, then transfer bone-side down to a medium-hot grill at around 350°F for 5–8 minutes to caramelize the sauce and add color.
You get the guaranteed tenderness of the oven with the finish of the grill.
FAQ
What’s the difference between St. Louis ribs and baby back ribs?
Baby back ribs are shorter, leaner, and cook faster.
St. Louis ribs are flatter, larger, and have more fat, which gives them richer flavor and makes them more forgiving when baking low and slow.
Can I make these ahead?
Yes — bake the ribs fully including the sauce, cool completely, then wrap tightly in foil and refrigerate for up to 3 days.
To reheat: wrap in foil and warm in a 300°F oven for 20–25 minutes, then add a fresh brush of sauce before serving.
Can I freeze leftover ribs?
Yes.
Wrap individual portions in foil, place in freezer bags, and freeze for up to 3 months.
Thaw overnight in the fridge and reheat as above.
What’s the best BBQ sauce for St. Louis ribs?
A sweet, tomato-based sauce works best with this dry rub and caramelizes beautifully in the oven.
Avoid thin, vinegar-forward sauces — they don’t reduce well in dry heat and can turn bitter. Make sure you check my Keto Bbq Sauce recipe out.

These are hands down the best ribs we’ve ever eaten. The instructions are banged on! Thanks so much for sharing we are eating them all.
I have a 1.31lb rack of St. Louis ribs, would the baking time be the same?
Thanks!
Yes, the same baking time.
Your rub recipe was awesome on our St Louis Ribs. The only thing I changed was I did a slow roast and baked them at 250 degrees. 4 1/2 lbs St Louis ribs, I cut the membrane off the back and cut the slab into 4 sections, used your rub recipe and then placed them on a rack meat side down inside of a roasting pan with foil lined on the bottom, and then covered the pan with foil. I slow roasted them at 250 degrees for about 2 hours, took them out and flipped them over and covered them with foil again and put them back into the oven for another 1 -1/2 hours. I took them back out of the oven, removed the foil completely, brushed a small amount of BBQ sauce over the top of the ribs, put them back in the over, did not cover them this time, and baked them for another 30 minutes. OMGOSH, they were so juicy, tender, and with your rub recipe, the taste was amazing! Thank you for your rub recipe!
Best ribs EVER!!!! They were fall off the bone tender and so flavorful. I think they were better than my local rib joint! Will definitely make these again.
Very tasty and easy … will definitely make this again.
Love this recipe, making it for the second weekend in a row today, thank-you!
Quick question, in the photo’s it looks like you’ve sprinkled flat leaf parsely on at the end but its nowhere in the ingredient list, or instructions. Thoughts?
Thanks,
Hi Jo-Anne, glad you like the recipe. The flat leaf parsley is totally optional and used only for garnishing. You can add it, if you’d like to. Have a great day!
Hi Mira, What a fantastic recipe! I made one rack tonight and it was tender in 90 minutes, so I added my favorite sauce, cooked the ribs 20 more minutes and they were delicious! Thank you for an easy, wonderful recipe!
Helpful hint, drop oven temp to 275F, after saucing, for the last 1/2 hour. 🙂
Great! Thank you!
It was my first time making ribs ever, and they came out delicious! I do think I’ll let the rub sit on the meat for a few hours before cooking next time. I let the rub sit for 15 minutes before putting them in the oven. I felt like some of the meat was not as flavorful as others. It may have just been the cut though. However, the meat came out tender and fell right off the bone.
