Easy St. Louis Ribs in Oven

These mouthwatering oven-baked St. Louis ribs are almost ridiculously easy to make. This recipe includes an easy homemade rub and tips to get tender, juicy ribs in the oven every single time!

Making St. Louis ribs in the oven is as easy as it gets. We start with our favorite dry rub — the perfect blend of sweet and savory with a little heat. We cook the ribs low and slow for maximum tenderness. And then we finish them off with a bit of barbecue sauce and a blast of high heat for perfect caramelization!

Ingredients to make ribs in oven

What are St. Louis ribs?

There are two types of pork ribs:

  • Baby back ribs come from the top of the rib cage. They’re shorter, more tender and leaner. They’re also more expensive.
  • Spare ribs are cut from the bottom of the rib cage. They’re larger, have more meat between the bone and more marbling, which equals more flavor!

But then what are St. Louis ribs? St. Louis ribs are just spare ribs that have been trimmed of the tips (which consist primarily of cartilage) and the extra flap of meat at the end. Cutting the ribs into a uniform shape makes them easier to cook and eat.

Key ingredients

This St. Louis ribs recipe calls for the following ingredients:

  • St. Louis ribs
  • Dry rub
  • Barbecue sauce

The dry rub

Our ideal dry rub for this ribs recipe is the perfect balance of sweet and smoky with a bit of spice! Here’s what you’ll need:

  • Kosher Salt: The coarse texture makes it perfect for sprinkling and less likely to clump together.
  • Brown Sugar: The sugar provides a little sweetness and helps with caramelization of the bark.
  • Smoked Paprika: Make sure you’re using a good-quality smoked paprika (I prefer a spicy version) for an intense smoky flavor. Regular paprika just won’t cut it for this recipe.
  • Ground Cumin: Cumin pairs extremely well with pork and adds a deep savory note to our rub.
  • Garlic Powder: Or feel free to substitute granulated garlic, in which case I would double the amount.

Step by step instructions

Prepping the ribs

To prep the ribs you’ll start by removing the membrane or silverskin, which is just the thin layer on the backside of the ribs. It’s completely edible, but can have an unpleasant papery texture when cooked.

Use a knife to gently remove a corner of the membrane and then just use your hands to peel it off. It can be slippery, so you can also use a paper towel for better grip if needed.

But don’t stress if you can’t find it — some stores will sell ribs with the membrane already removed. For more information on removing the membrane, check out this article.

Baking the ribs

We cook the ribs in two steps to achieve tender, juicy perfection:

  1. Tightly wrap the ribs in aluminum foil. Cook for 2 hours at 250°F (120°C).
  2. Unwrap the ribs. Continue cooking for 2 hours or until tender.

The first step traps steam, which creates tender ribs while keeping them moist. But it also prevents a nice bark from forming. Which is why we cook the ribs unwrapped for the final hour or two.

The finish

To get the perfect bark (the crispy layer of spices that forms on the outside of the ribs), we like to baste with bbq sauce and finish with high heat for a bit of delicious caramelization. You can do this with a grill or by placing the ribs under the broiler for 5-10 minutes.

Both methods will give you fall off the bone tender ribs with a nice bark, but I definitely prefer finishing our oven-baked St. Louis ribs on the grill. It gives the meat a beautifully caramelized exterior with a bit of delicious charring.
