Since I'm still spending quite a bit of time at the hospital with my husband, I made these the evening before. Quite often, that works best for things that need to cook for a long time. I can start cooking before dinner, and it's done before I go to bed. The next day, I just heat and serve when I get home.
There are probably thousands of recipes for rib rubs. I used on I bought on vacation. If you don't have a prepared rub, a sprinkle of salt, pepper and some paprika will do. Or seasoned salt if you have that. Sure, you can get all fancy, but that's for another day.
As far as the sauce, use one you like. I've been known to dabble with making barbecue sauce, but there are quite a few commercial ones that I like as well.
Oven-Baked "Barbecue" Ribs
1 teaspoon rib rub (or as needed)
1/4 cup barbecue sauce (plus more, as needed)
Line a baking sheet with aluminum foil (for easy cleanup) and preheat the oven to 225 degrees.
Sprinkle the ribs all over with the rib rub. Place the ribs, bone-side down, on the baking sheet. Bake at 225 degrees until the ribs are cooked to your desired doneness - from 3 to 5 hours.
About 30 minutes before the ribs are done to your liking, slather the ribs with the sauce, then continue cooking.
When the ribs are done, let them rest for a few minutes before cutting then apart. If you won't be eating them immediately, let them cool, then refrigerate.
Serve with extra sauce, as needed.
