How to Slow Cook Ribs in the Oven: Step-by-Step Guide

Follow these precise steps for fall-off-the-bone ribs with minimal effort:

Step 1: Prepare the Ribs

  • Remove the membrane from the bone side of the ribs for better seasoning penetration.
  • Pat ribs dry with paper towels for better spice adhesion.

Step 2: Make the Spice Rub

  • Combine 2 tbsp paprika, 1 tbsp brown sugar, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp smoked paprika, 1/2 tsp salt, 1/4 tsp black pepper, and pinch of cayenne (optional).
  • Generously coat ribs with rub on all sides, pressing into the meat.

Step 3: Preheat and Cook

  • Preheat oven to 275°F (135°C) for optimal low-and-slow cooking.
  • Place ribs on a wire rack over a foil-lined baking sheet (or roasting pan).
  • Cover tightly with aluminum foil to retain moisture.
  • Bake for 2.5 hours (baby back ribs) or 3 hours (spare ribs).

Step 4: Check Doneness

  • Use a meat thermometer to confirm internal temperature reached 190°F (88°C).
  • Meat should pull back from bones by 1/4 inch and bend easily when lifted with tongs.

Step 5: Finish with Sauce

  • Remove foil, brush with barbecue sauce.
  • Return to oven for 10-15 minutes to caramelize sauce.
  • Let rest 10 minutes before serving for juicier results.

Pro Tips for Perfect Oven-Ribs

  • Choose the right ribs: Baby back ribs cook faster (2-2.5 hours); spare ribs need 3+ hours for maximum tenderness.
  • Never skip the thermometer: Internal temperature of 190°F ensures perfect doneness without overcooking.
  • Use a wire rack: Elevates ribs for even heat circulation and prevents soggy bottoms.
  • Double-wrap foil: Prevents leaks and maintains consistent moisture during cooking.
  • Broil for crust: For extra caramelization, broil 2-3 minutes after saucing (watch closely to avoid burning).

Frequently Asked Questions

How long does it take to slow cook ribs in the oven?

Baby back ribs: 2-2.5 hours at 275°F. Spare ribs: 3-3.5 hours. Always verify doneness with a meat thermometer (190°F internal temperature).

Should I wrap ribs in foil when slow cooking in the oven?

Yes. Wrap tightly in foil for the first 2-3 hours to retain moisture and speed up tenderizing. Remove foil for the last 10-15 minutes to caramelize sauce.

What's the best temperature for slow cooking ribs in the oven?

275°F (135°C) is ideal. Lower temperatures (225°F) require longer cooking but may dry out ribs. Higher temperatures (300°F+) risk toughening the meat.

How do I know when slow-cooked ribs are done?

Internal temperature must reach 190°F. Visually: meat pulls back 1/4 inch from bones, bends easily when lifted with tongs, and feels tender but not mushy when pressed.

Can I use a regular baking sheet instead of a roasting pan?

Yes. Line baking sheet with foil, place wire rack on top, and position ribs on rack. Use a second sheet pan underneath to catch drippings for easy cleanup.

Do I need to add liquid when slow cooking ribs in the oven?

No—foil trapping moisture makes liquid unnecessary. If not using foil, add 1/2 cup apple juice or broth to the pan to prevent drying.

Conclusion

Slow cooking ribs in the oven delivers restaurant-quality results with minimal effort. By following precise temperatures, exact spice measurements, and using the right tools, you'll consistently achieve tender, flavorful ribs that impress every time. Remember: thermometer accuracy and proper resting time are the secrets to perfection.
