Oven Slow-Cooked Pork Ribs Recipe: Step-by-Step Guide for Perfect Fall-Off-The-Bone Ribs

Here's how to make perfect oven slow-cooked pork ribs with this detailed recipe. This guide includes exact measurements, step-by-step instructions, and professional tips for tender, flavorful ribs that fall off the bone every time. Whether you're a beginner or experienced cook, you'll learn everything you need to know to achieve restaurant-quality results at home.

Ingredients

• 2 racks of pork ribs (baby back or spare ribs, about 3-4 pounds total)
• 3 tablespoons brown sugar
• 2 tablespoons smoked paprika
• 1 tablespoon garlic powder
• 1 tablespoon onion powder
• 1 teaspoon ground cumin
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon cayenne pepper (optional for heat)
• 1/4 cup apple cider vinegar
• 1/4 cup apple juice or broth

Step-by-Step Instructions

1. Prepare the ribs: Remove the membrane from the bone side of the ribs. Slide a butter knife under the membrane at one end, then grip it with a paper towel and pull it off completely. This ensures better flavor absorption and tender meat.
2. Mix the dry rub: In a small bowl, combine brown sugar, smoked paprika, garlic powder, onion powder, cumin, salt, black pepper, and cayenne (if using). Mix thoroughly.
3. Apply the dry rub: Pat the ribs dry with paper towels. Rub the spice mixture evenly over both sides of the ribs, using about 2 tablespoons per rack. Press gently to help the spices adhere.
4. Preheat oven: Preheat oven to 275°F (135°C). Position rack in the center of the oven.
5. Prepare roasting pan: Place a wire rack inside a large roasting pan. Pour apple cider vinegar and apple juice into the bottom of the pan (about 1/4 inch deep).
6. Cook ribs: Place ribs bone-side down on the wire rack. Cover the pan tightly with aluminum foil. Bake for 2.5 hours for baby back ribs or 3 hours for spare ribs.
7. Check doneness: After 2.5 hours, check internal temperature with a meat thermometer. Ribs are done when they reach 190-203°F (88-95°C) and the meat pulls back from the bones by about 1/4 inch.
8. Optional crisp finish: For crispy exterior, remove foil and increase oven temperature to 350°F (175°C). Bake uncovered for 15-20 minutes until surface is caramelized.
9. Rest before serving: Let ribs rest for 10-15 minutes before cutting. This allows juices to redistribute for maximum tenderness.

For best results, use 1-2 tablespoons of your chosen spice blend per rack of ribs. Adjust quantities based on personal taste preferences.

Oven Techniques for Perfect Results

These proven techniques ensure tender, juicy ribs every time:

• Temperature control: Maintain consistent 275°F (135°C) throughout cooking. Use an oven thermometer to verify accuracy—many home ovens have temperature variations of 25°F or more.
• Liquid management: Add 1/4 cup liquid (apple juice, broth, or vinegar) to the pan bottom. This creates steam that keeps ribs moist without making them soggy.
• Foil wrapping: Wrap ribs tightly in heavy-duty aluminum foil after 1 hour of cooking. This traps moisture and speeds up tenderization. For extra flavor, add 1 tablespoon of butter or honey inside the foil packet.
• Crisp finish method: For caramelized exterior, remove foil during the last 15-20 minutes at 350°F (175°C). Baste with your favorite BBQ sauce during this stage for maximum flavor.
• Resting time: Never skip the 10-15 minute rest period. This allows juices to redistribute throughout the meat, preventing dryness when cutting.

Essential Tools for Perfect Ribs

Meat Thermometer

A reliable thermometer is critical for checking internal temperature. The ThermoPro TP-1900 provides accurate readings within 3 seconds and has a wide temperature range (0-572°F). For ribs, aim for 190-203°F (88-95°C) for perfect tenderness.

Heavy-Duty Roasting Pan

A quality roasting pan ensures even heat distribution. The Le Creuset Enamel-on-Steel Roasting Pan features a non-stick surface and built-in rack for optimal air circulation. Choose one large enough to hold 2 racks of ribs with 1-2 inches of space around them.

Heavy-Duty Aluminum Foil

Standard foil tears easily. The Kraft Paper Wrap with Aluminum Foil is 50% thicker than regular foil, preventing leaks during the long cooking process. Use two layers when wrapping ribs for maximum moisture retention.

Quality Spice Blends

Pre-made blends save time while ensuring balanced flavors. The McCormick Grill Mates Original Rub contains exactly the right proportions for ribs, with no added fillers. For specialty blends, look for brands that list all ingredients clearly.

Silicone Basting Brush

For applying sauces during the crisp finish stage, the OXO Good Grips Silicone Basting Brush withstands high heat and cleans easily. Its flexible bristles reach between bones for even sauce coverage without tearing the meat.

Frequently Asked Questions

How long should I cook pork ribs in the oven for slow cooking?

For perfect slow-cooked ribs, cook at 275°F (135°C) for 2.5 to 3 hours. Baby back ribs typically need 2.5 hours, while spare ribs require 3 hours. The ribs are done when they reach an internal temperature of 190-203°F (88-95°C) and the meat pulls back from the bones by about 1/4 inch. Always use a meat thermometer for accuracy.

Should I remove the membrane from pork ribs before slow cooking?

Yes, removing the membrane (silver skin) is essential. This thin layer prevents flavors from penetrating the meat and becomes tough during cooking. To remove it: slide a butter knife under the membrane at one end, lift it, then grip with a paper towel and pull it off completely. This step makes a significant difference in tenderness and flavor absorption.

Do I need to flip the ribs while slow cooking in the oven?

No, flipping isn't necessary when slow cooking ribs in the oven. The low, even heat circulates around the ribs on a rack, cooking them uniformly from all sides. Flipping could damage the meat and disrupt the cooking process. If you're using a roasting pan with a rack, the hot air flows freely around the ribs for consistent results.

Can I use frozen ribs for oven slow cooking?

It's not recommended to cook frozen ribs directly. Thaw ribs completely in the refrigerator for 24-48 hours before cooking. Cooking frozen ribs leads to uneven cooking, extended cooking times (add 50-60% more time), and potential food safety issues. If you must cook frozen ribs, increase cooking time by 30-60 minutes and check internal temperature frequently to ensure they reach 190-203°F (88-95°C) throughout.

How should I store and reheat leftover ribs?

Store leftover ribs in an airtight container in the refrigerator for up to 4 days. To reheat, wrap ribs in aluminum foil with 1-2 tablespoons of broth or apple juice to maintain moisture. Heat in a 300°F (150°C) oven for 20-30 minutes until warmed through. Avoid microwaving, as it makes ribs tough and rubbery. For best results, reheat only what you plan to eat immediately.

Can I finish ribs on the grill after oven cooking?

Absolutely! Many professional pitmasters use the "oven then grill" method for perfect ribs. After slow cooking in the oven until nearly done (internal temperature 180-185°F), finish the ribs on a medium-hot grill (350°F/175°C) for 5-10 minutes per side. This adds smoky flavor and creates a beautiful caramelized exterior while keeping the meat tender inside. Brush with BBQ sauce during the last 2-3 minutes for maximum flavor.

Conclusion

Oven slow-cooked pork ribs deliver restaurant-quality results with minimal effort. By following this detailed recipe with exact measurements and professional techniques, you'll achieve fall-off-the-bone tenderness and rich flavor every time. Remember the key principles: remove the membrane for better flavor absorption, maintain consistent oven temperature, use a meat thermometer for accuracy, and allow proper resting time. With these simple steps, you'll master the art of oven ribs and impress everyone at your next gathering.

Don't be afraid to experiment with different spice blends and finishing techniques. The best part of cooking is personalizing recipes to your taste preferences. Happy cooking!
