What kind of beef ribs to buy for slow roasting in the oven? 

Beef ribs are sold two ways, as full slabs or short ribs. For this recipe use the full slab style ribs. Short ribs are best in a braising liquid made of deep rich stock and cooked for hours until the meat literally melts off the bone.

Beef ribs are similar to pork ribs in their appearance and cooking method. Pork meat is sweeter, so you’ll notice there is a difference in taste. Beef ribs taste more like a steak!

While it can be hard to find beef ribs, you can always ask your local butcher or anyone in the meat department for them. Added bonus, while they are getting them ready for you, ask them to remove the silver skin so you don’t have to.


  • 1-2 Racks Beef Ribs – Not to be confused with short ribs, as they use two different cook methods.
  • Salt and Pepper – A simple seasoning to bring out the flavor of the beef.
  • Bottle of Lager – Beer in BBQ sauce gets cooked down leaving a delicious deep flavor, without the alcohol!
  • Brown Sugar – A staple in many BBQ sauce recipes, adds a beautiful sweetness.
  • Butter – It adds to the silky texture of the sauce.
  • Molasses – Gives BBQ sauce a dark, smoky flavor and color.
  • White Vinegar – A little acid used to create a tangy taste as well as to help balance out the rich flavors and cut through the heaviness.
  • Yellow Mustard – This will give it a hint of tartness.
  • Cajun Seasoning – Incredible seasoning made up of a combination of spices. Gives it both flavor and heat.
  • Chili Powder – A different flavor and heat, pairs well with the Cajun seasoning.
  • Tomato Paste – A more concentrated tomato flavor than tomato sauce. A little goes a long way.

The secret to perfectly cooked beef ribs in the oven

This recipe uses a two-step process to not only permeate the meat with flavor from the mop, but the mop is also used to create a caramelized exterior to the beef ribs. The braising mop is poured over the top of the ribs in a foil packet and the steam in the first cook helps keep the ribs nice and moist while infusing the deep flavors of the mop into the ribs.

Once the ribs are taken out of the foil packet and the sauce has been allowed to permeate throughout, the ribs are glazed once more and cooked open in the oven for the last round. This time at a higher temperature give it a caramelization and a deep brown color.

How many beef ribs per person

Ribs are an economical way to serve a crowd for summer BBQs or casual outdoor dinners. Plan on 2 ribs per person, then add 2-4 more for more hearty eaters.  They are great the next day so if you have leftovers they are easy to warm up in the oven.

How to cook Beef Ribs in the Oven

  • To prep, you’ll need to make the mop/braising sauce, preheat the oven to 300° and line a pan with foil.
  • Season the ribs with salt and pepper.
  • Create a foil packet, large enough for the entire rack to lay down. There should be a small opening created to add 1/2 cup of the mop poured over the top of the ribs, before sealing the packet. Repeat with the second rack of ribs if necessary.
  • Place foil packets on top of the prepared sheet(s) and slow roast for 1/5 hours, during which time you’ll boil the remaining sauce on the stove to reduce and thicken.
  • Remove ribs from the oven and open the bags to release the steam. Once they are cool enough to handle, transfer to a separate sheet or plate. Clean off (or prepare new) the baking sheet and replace it with new foil.
  • Remove ribs from foil packets and place them onto the newly prepared sheet.
  • Increase the heat to 375° and brush thickened BBQ sauce onto the ribs. Place back in the oven for 30 minutes to caramelize.
  • Cut into 2 bone pieces and serve.

How to grill this recipe for meaty beef ribs?

These beef ribs are easily adapted on the grill. Follow the exact instructions, but use a method of indirect heat grilling. On a gas grill you’ll have the gas going on one side (or on either side) and place the ribs on top of the area where there is no heat. You’ll want to have the gas on low to make sure it cooks slowly.

If you have a charcoal grill you’ll create a 2 zone heat with the charcoal only on one side and place the foil packed on the other no heated side.
