Just heat your oven to 375°, take out frozen ribs or defrosted ribs from packet (Costco beef ribs are good), take baking tray wrap with foil and just place ribs on tray with foil wrap in bottom.
You don’t need to cover it ,,, just bake for around 1 hour, then take out, sprinkle with salt pepper and some garlic powder and pepper and eat! Super easy.
