Quick Answer
Baking frozen cooked ribs usually takes 1-3 hours at 250-325°F. The exact time depends on the type and size of ribs. Baby back ribs take 1-2 hours while spareribs can take up to 3 hours. Thinner cut ribs bake faster than thick country-style ribs. Always rely on a meat thermometer over time, not just a timer. Ribs are done when they reach 160-185°F internally.
Detailed Answer
Baking already cooked frozen ribs is a convenient way to quickly reheat them while restoring moisture and flavor. Here is a detailed guide on how long to bake frozen cooked ribs:
Thaw The Ribs First
It is best to thaw frozen ribs before baking to ensure even cooking. There are a few thawing methods:
- Refrigerator thawing: Place ribs in a rimmed baking sheet. Thaw overnight or for at least 8 hours in the refrigerator.
- Cold water thaw: Seal the frozen ribs in a plastic bag submerging it in cold tap water. Change the water every 30 minutes. This may take 2-3 hours for a full rack.
- Microwave thawing: Partially thaw ribs in the microwave in 5-minute increments, turning over between sessions. This works best for smaller individual portions.
Thawed ribs bake faster than frozen. If short on time, preheat the oven while thawing as it will continue to thaw while baking.
Choose A Baking Temperature Between 250-325°F
The ideal temperature for baking ribs is somewhere between 250-325°F. Higher temperatures around 325°F, bake ribs up to 30% faster. Lower 250°F temperatures result in more tender, fall-off-the-bone ribs.
Here are oven temperatures and approximate baking times for different types of ribs:
| Rib Type | Oven Temperature | Approximate Bake Time |
|---|---|---|
| Baby Back Ribs | 325°F | 1 – 1 1/2 hours |
| Baby Back Ribs | 250°F | 1 1/2 – 2 hours |
| Spareribs | 325°F | 2 – 2 1/2 hours |
| Spareribs | 250°F | 2 1/2 – 3 hours |
| Country-style Ribs | 325°F | 1 1/2 – 2 hours |
| Country-style Ribs | 250°F | 2 – 2 1/2 hours |
The thickness and exact weight of the ribs affect baking time. Time ranges are provided for approximate guidance.
Rely On A Meat Thermometer For Doneness
While the baking time can provide an estimate, always rely on a meat thermometer to check doneness, not just a timer. Insert an instant-read thermometer into the thickest part of the ribs.
Different temperatures indicate the level of doneness:
- 160°F = Good for those who prefer drier ribs with some chew.
- 170°F = Juicy, tender ribs.
- 185°F = Very tender with meat pulling away from the bones.
The USDA recommends cooking ribs to at least 160°F for food safety. For fall-off-the bone ribs, aim for 185°F.
How To Bake Frozen Cooked Ribs
Follow these simple steps for baking frozen cooked ribs to hot, juicy perfection:
- Thaw ribs completely using the refrigerator, cold water, or microwave method.
- Preheat oven to 250-325°F. Use higher heat for faster baking.
- Line a rimmed baking sheet with foil and lightly grease it.
- Arrange ribs meaty side up on the baking sheet without overcrowding.
- Bake for estimated time based on cut of ribs and oven temperature.
- Brush bbq sauce or glaze on ribs during last 15-30 minutes if desired.
- Check temperature using a meat thermometer for doneness.
- Allow ribs to rest 5-10 minutes before serving.
- Slice into individual ribs and enjoy!
Tips For the Best Reheated Ribs
Follow these tips for ribs that come out juicy, flavorful and hot:
- Always thaw ribs thoroughly before baking.
- Remove the membrane from the bone side for tender texture.
- Brush ribs with oil or bbq sauce before baking for added moisture and flavor.
- Spritz ribs with apple juice or water if they appear dry while baking.
- Make foil tents to prevent over-browning if needed.
- Allow ribs to rest before cutting for juicier results.
Common Questions
Can you bake ribs from frozen?
Yes, it is possible to bake ribs directly from frozen. However, thawing first allows ribs to bake more evenly throughout. Frozen ribs may burn on the outside before the center is fully heated.
Should you wrap ribs when baking?
Wrapping ribs in foil or baking them covered is optional. Covering concentrates moisture and steam which makes the ribs extra tender. However, uncovered ribs develop a nice crust. Monitor the browning and cover with foil if ribs are drying out or over-browning.
How long do baked ribs last in the fridge?
Cooked ribs will keep 3-4 days refrigerated. Reheat leftover baked ribs in a 350°F oven until hot, about 20 minutes. Freeze ribs for 2-3 months for longer storage.
Conclusion
Baking frozen cooked ribs makes enjoying this barbecue favorite quick and easy. Thaw the ribs completely first for the most even results. Bake at 250-325°F until ribs reach 160-185°F internally based on desired doneness. Baby back ribs take 1-2 hours to reheat while spareribs need up to 3 hours. Rely on a meat thermometer over recommended baking times for accuracy. With the right technique, reheated baked ribs taste just as delicious as ones fresh off the grill.
