Simplest thing u can do is the following:
Season with salt, pepper, garlic, onion, and paprika all in equal parts (don't oversalt) and no sugar because of the temp below.
Put on a roasting rack if you have one and put on a backing sheet that hast like 1/4-1/2 inch rim so grease doesn't leak out into your oven.
If you have no roasting rack then just set them in that pan bone side down.
Put oven on 325F. If you have your smoker meat thermometer then put it in the ribs and pull them when the IT is 195-198F or higher if u want fall off the bone texture.
Sugar can burn and get bitter so if you want sweetness the last 15 min you can sprinkle sugar on or just mop some bbq sauce on and let it caramelize and pull the ribs.
Don't wrap, don't cover, don't spritz, don't mop, don't baste, don't use a water pan, just let it roll.
This is as simple as you can make it unless you don't want to season it at all hahaha.
What you will get is a rack of ribs with great bark, great flavor, and great texture.
These will be super similar to smokes ribs but without the smoke. That's it!
I hope this helps
