Combine baby back ribs, onion, olive oil, lemon juice, oregano, honey, garlic, salt, and pepper in a large resealable plastic bag. Turn to ensure ribs are well coated.

Step 2

Marinate in the refrigerator, turning occasionally, 4 to 8 hours.

Step 3

Preheat oven to 400 degrees F (200 degrees C). Line a baking sheet with aluminum foil; grease with cooking spray.

Step 4

Arrange ribs on the prepared baking sheet, leaving space between them.

Step 5

Bake in the preheated oven until browned, about 10 minutes. Reduce oven temperature to 300 degrees F (150 degrees C). Continue baking until ribs are tender, about 1 hour.
