Ingredient Notes
- Baby back ribs: Try to find meaty slabs of baby back pork ribs for extra good ribs! Remember that the silver skin membrane needs to be removed beforehand, instructions below.
- Mustard: Use either yellow or Dijon mustard as the binder for the spices.
- Yellow onions and butter: Both of these go into the foil packets. Thinly sliced onions will provide aromatic flavor and act as a bed for the ribs to help circulate heat, while the butter melts for rich flavor.
- The dry rub for ribs: Brown sugar, smoked paprika, chili powder, ground cumin, garlic powder, onion powder, Kosher salt and pepper.
- BBQ Sauce: Grab your favorite bottled BBQ sauce is for brushing at the end and serving.
- You’ll also need aluminum foil. For each, I use about 3-4 layers of heavy duty foil for better heat retention and to prevent leakage, so make sure you have enough.
This recipe makes 2 full racks. If making only one, simple cut the ingredients by half. Quantities in the recipe card below.
Variations and Substitutions
- BBQ sauce choices: I have an easy apple cider bbq sauce (great for fall) and an amazing homemade sweet bbq sauce.
- Prefer to use St. Louis style ribs? They are fattier, meatier, and have more connective tissue, which offers more flavor but requires a longer cook time (usually 4+ hours) to become tender.
- Want to make it on your crockpot? My Slow Cooker Baby Back Ribs cook in 6 hours.
- Try a different flavor profile with my baked Chinese BBQ Ribs recipe. It’s a family favorite!
How To Cook Baby Back Ribs in the Oven
Prepping for oven baked baby back ribs takes just 20 minutes, and the rest is just oven time. It’s easy!
Step 1 | Make the dry rub for ribs
Preheat the oven to 275°F. Yes, low temperature is what we’re going for with these oven baked ribs recipe. Combine the dry rub ingredients (listed in the recipe card below) and mix until evenly combined.
Step 2 | Prep the baby back ribs
Remove the membrane. This is an important step! The outer membrane on the back side is tough and chewy, and needs to come off. Here’s how: Starting at one end, slide a paring knife under the membrane until it loosens, then carefully peel it off all the way across to the other side.
Step 3 | Season the ribs
Binder for the seasoning: Brush both sides of the ribs with mustard. I use about 1 tablespoon of mustard per side. You won’t be able to taste it; it’s just the binder.
Apply the seasoning: Then, sprinkle your dry rub onto the ribs and season generously on all sides.
Step 4 | Assemble and bake
Stack 3-4 large sheets of aluminum foil on top of each other on a large sheet pan. This helps to trap heat better and prevents the juices from leaking.
Arrange the sliced onions in the center. These will slightly elevate the ribs, providing moisture and flavor, and also improving heat circulation. Place the prepared ribs on top, meaty side facing up. Top with 2-3 tablespoon of butter (spread out), then wrap it up and ensure it’s sealed very tightly. Repeat with the other rack of ribs.
Why add butter: It adds richness and flavor to the juices. Cut the butter into pieces and arrange it on top.
Place them both on a baking sheet, if they fit. If not, use two sheet pans. Bake the ribs at 275°F for 3 hours undisturbed.
Step 5 | Brush with BBQ sauce and broil
Once they’re fully cooked and tender, carefully open the packets. Steam will escape, so be careful. The ribs should be very fall-apart tender!
Brush them with a generous amount of BBQ sauce and broil for 3-5 minutes until slightly charred and caramelized on top.
And there you have it, the absolute BEST and EASIEST oven baked bbq ribs!
Tips for Success
- Season generously. You can always make more if you need it, but don’t be shy. You want it to build flavor!
- Use several layers of foil, preferably heavy-duty to prevent leakage and to keep the heat and moisture well contained.
- You need an extra large sheet pan to fit the ribs. Make sure they don’t hang over.
- Do not use white sugar. Use brown sugar. Granulated white sugar will caramelize and harden.
- Let the oven baked ribs rest. If you’ve got the extra time, it’s a good idea to let the ribs rest in the packets for about 10 minutes. This will redistribute the juices and keep them extra tender.
- Don’t skip the broiling at the end! If you love the caramelized bits, this is a must for the ultimate flavor. Brush with your favorite BBQ sauce.
How Long to Cook Ribs in the Oven
This is the question I get asked the most! They need 3 hours at 275°F for true fall-off-the-bone tender oven baby back ribs.
If you need to get precise, aim for an internal temperature between 190°F and 205°F. While ribs can start to become tender around 190°F, taking them past 200°F allows the connective tissues to fully break down. So the longer, the better!
Can I use a different temperature or time for the oven? Yes, increase the temperature to 300°F and bake for 2.5 hours instead.
Recipe FAQs
I’d recommend thawing them first. Otherwise the mustard and seasoning won’t stick, and it will also turn out soggy and watery from the excess moisture.
They should be soft enough to pull off the bone easily after 3 hours. The internal temperature should be between 190°F and 205°F when they get tender.
To get that tender texture, you need to wrap them in foil tightly to seal in the moisture and steam. If you bake them uncovered, they will get dry and tough.
The membrane is tough and chewy, so I’d highly recommend removing it.
No, the mustard is only used as a binder. You won’t be able to taste the mustardy flavor after the long cooking time.
Dry Rub for Ribs: Variations
- Brown Sugar and Chipotle: Brown sugar, chipotle powder, smoked paprika, garlic powder, onion powder, salt, pepper.
- Ancho Chili Rub: Ancho chili powder, brown sugar, cumin, garlic powder, onion powder, salt, pepper.
- Lemon Pepper: Lemon pepper salt, garlic powder, onion powder, brown sugar.
- Spicy dry rub: Chili powder, cayenne pepper, cumin, paprika, garlic and onion powder, salt, pepper.
Make Ahead and Freezing
Make ahead: Season the ribs 1 day before, refrigerate overnight and about 30 minutes before baking, bring them out closer to room temperature. Assemble and bake as directed.
Freezing: Once cooled, wrap them tightly in foil and transfer to a freezer bag. Freeze for up to 3 months. Thaw in the fridge overnight.
Reheating: I like to reheat them straight in the foil packets at 325°F until warm, Brush with a fresh coating of BBQ sauce and broil.
What to Serve with Ribs
These oven baked baby back ribs can be served with all kinds of side dishes no matter the season! Try these.
Summer sides: Watermelon Feta Salad, Avocado Corn Salad, and Grilled Peach Salad.
Another staple that gets cooked low and slow indoors is this Slow Cooker Beef Brisket. Give it a try!

Oven Baked Baby Back Ribs (Fall-off-the-Bone!)
Equipment
- 2 Extra large sheet pans enough to fit a rack of ribs
Ingredients
- 2 racks baby back ribs - about 3-3.5 lbs each, find meaty ones
- 4 tablespoons yellow or dijon mustard
- 1 cup of your favorite BBQ sauce - for brushing, plus more for serving
- ½ of a large yellow onion - thinly sliced
- 6 tablespoons butter - cut into pieces
Dry rub for ribs:
- 2 tablespoons brown sugar - light or dark
- 1 tablespoon smoked paprika - use "smoked" paprika, not regular
- 1 tablespoon chili powder
- 1 tablespoon garlic powder
- 2 teaspoons ground cumin
- 2 teaspoons onion powder
- 1 tablespoon Kosher salt
- 1 teaspoon ground black pepper
Instructions
- Preheat oven to 275ºF. We’re going for a low oven temperature here.
- Make the dry rub for the ribs: In a bowl, mix all the dry rub ingredients until evenly combined. Set aside.
- Prep the ribs: Remove the outer membrane from the back side of the rack of ribs. Here’s how – on one end of the ribs, run a paring knife through the outer membrane layer until the layer starts to loosen and separate. Then carefully peel off the membrane all the way to the other side (use paper towel if needed for a better grip). Discard the membrane.
- Season ribs: Brush the ribs on both sides with mustard, I use about 1 tablespoon of mustard per side. The mustard will help the seasoning stick. Apply the dry rub over the ribs generously on all sides, pressing lightly to adhere.
- Assemble: Stack 3-4 large layers of aluminum foil on top of each other, over a large sheet pan. This prevents leaking and promotes better heat retention. Next, place the onions on top of the foil, followed by a rack of ribs, meaty side side up. Scatter about 3 tablespoons of butter on top of the ribs evenly. Seal the foil packets very tightly. Repeat this process with the second rack of ribs.
- Bake: Arrange both of the racks of robs on a large sheet pan, or use 2 sheet pans. Make sure it fits, they shouldn't hang over the pan. Bake at 275ºF for 3 hours. When ready, open the packets, they should be tender by now. If not, they need more time.
- Brush with BBQ sauce and broil: Brush the ribs generously with BBQ sauce, then broil for 3-5 minutes until slightly charred and caramelized on top. Enjoy!
Notes
- Baby back ribs: Pick one that looks meaty!
- Removing the membrane from the ribs: It’s necessary to remove the silver skin on the back of the ribs using a paring knife and paper towel for grip; otherwise, they will be tough.
- Oven temperature: Preferably 275°F for 3 hours (or 300°F for 2.5 hours, but may not be as tender).
- Doneness: Aim for an internal temp of 190°F–205°F to make sure it’s tender.
- How to improve heat circulation for the ribs: Place ribs on a bed of sliced onions and top with 2 tbsp butter before sealing. This creates a natural “rack” and braises the meat with more flavor.
- Use 3-4 layers of aluminum foil (preferably heavy duty) for proper heat retention and to prevent the juices from leaking.
- When broiling, keep an eye on the ribs so they don’t burn, broiling happens fast.
- Make ahead: Apply dry rub the night before; refrigerate overnight. Let sit at room temp for 30 mins before baking as directed.
- Storage: Store in foil/airtight container for 3-4 days.
- Freezing: Wrap tightly in foil and place in a freezer bag for up to 3 months. Thaw in fridge.
- Reheating: Heat in foil at 325°F for 20-30 mins, then brush with sauce and broil.
- Baby Back Ribs: Leaner (but still succulent!), smaller, and more tender. They cook faster (~3 hours) and come from high on the back.
- St. Louis Style: Meatier, flatter and contains more fat and connective tissue, which offers more flavor but requires a longer cook time (usually 4+ hours) to become tender.
- Mustard: Use yellow or Dijon mustard to help spices stick (you won’t be able to taste the mustard).
- Use brown sugar only; white sugar can harden.
- Spices: Feel free to customize the dry rub. Use anything you’d like!
