Preheat the oven to 400 degrees Fahrenheit.
Chop the potatoes, onion, and pepper into small pieces and add to a large bowl.
Toss with the olive oil and minced garlic until everything is well coated.
Add in the spices, salt, and black pepper and mix until well incorporated.
Add to a baking dish and bake for 25 minutes. You shouldn't need to grease the baking dish since the potatoes are all oiled up!
After 25 minutes, turn up the heat to 425 and bake an additional 10-15 minutes to help brown the potatoes. You'll know they're done when they can be easily pierced with a fork.
Serve with ketchup, additional salt and pepper, salad, or any other brunch eats!
