Why This Recipe Is So Special

Oven fried potatoes and onions are irresistible because they combine textures, flavors, and aromas in one dish:

• Crispy, golden edges: Achieved by careful slicing, even oil distribution, and finishing under the broiler.
• Tender potato interiors: Red potatoes or Yukon Golds maintain shape and fluffiness when baked.
• Caramelized sweetness: Onions slowly bake to release natural sugars, adding depth.
• Smoky richness: Bacon infuses the dish with savory aroma and indulgent flavor.
• Buttery coating: Butter helps create golden color, luscious mouthfeel, and a rich finish.

Combined, these elements transform humble ingredients into a side dish that feels comforting, nostalgic, and satisfyingly indulgent.

Ingredients & What Each One Does

• 5 pounds red potatoes: Thinly sliced or cubed; red potatoes hold their shape, crisp beautifully, and provide a slightly waxy texture that contrasts with tender interiors.
• 1 large onion, finely chopped: Adds natural sweetness that complements the earthiness of potatoes; caramelizes during baking to deepen flavor.
• 6 slices bacon, chopped: Provides smoky, savory richness; renders fat that helps potatoes crisp and adds flavor complexity.
• ½ cup butter, diced: Coats the potatoes for golden browning and adds luxurious richness; a combination of butter and bacon fat creates irresistible texture.
• Salt and freshly ground black pepper: Essential seasoning that enhances all flavors; balances the sweetness of onions and richness of bacon and butter.
• Optional fresh herbs: Rosemary, thyme, or parsley add aromatic freshness and visual appeal.
• Optional garlic or smoked paprika: Boosts flavor with a subtle smoky or savory twist.

Essential Tools & Equipment

• Large mixing bowl for tossing ingredients evenly
• 9×13-inch casserole dish or roasting pan
• Sharp chef’s knife and cutting board
• Measuring cups and spoons for accuracy
• Aluminum foil to trap steam during baking
• Spatula or wooden spoon for stirring and layering
• Wire rack (optional) for cooling or broiling for crispier edges

Step-by-Step Instructions

1. Preheat & Prepare: Preheat oven to 400°F (200°C). Lightly grease a 9×13-inch casserole dish with butter or nonstick spray. This ensures easy cleanup and prevents sticking.
2. Slice the Potatoes: Wash and scrub potatoes. Leave skins on for rustic flavor or peel if desired. Slice evenly about ¼-inch thick for uniform baking. Even slices guarantee crisp edges and tender centers.
3. Prepare Onions and Bacon: Chop onions finely so they cook evenly. Cut bacon into small pieces. The combination of bacon fat and butter will coat the potatoes and onions during baking.
4. Toss Ingredients Together: In a large bowl, combine potatoes, onions, bacon, diced butter, salt, and pepper. Toss until all pieces are evenly coated, ensuring each slice has a bit of butter and seasoning.
5. Layer in Casserole Dish: Spread mixture evenly in the prepared dish. Ensure potatoes are in a single layer as much as possible for even cooking. Cover tightly with aluminum foil for the first 45 minutes to trap moisture and prevent drying out.
6. Bake Covered: Bake in the preheated oven for 45 minutes. This allows potatoes to cook through while onions soften and flavors meld.
7. Uncover & Stir: Remove foil carefully. Gently stir the potatoes and onions to redistribute fat and seasonings, promoting even browning.
8. Broil for Crispy Edges: Switch oven to broiler mode. Broil for 5–7 minutes, stirring every minute to prevent burning and ensure golden, crispy surfaces.
9. Check for Doneness: Potatoes should be tender inside with crispy edges. Adjust broiling time if necessary.
10. Serve Hot: Transfer to plates or a serving dish. Garnish with chopped fresh herbs or a sprinkle of smoked paprika for extra flavor and presentation.

Make-Ahead, Storage & Reheating

• Leftovers keep in an airtight container in the refrigerator for up to 3 days.
• Reheat in a 350°F (175°C) oven for 10–15 minutes to restore crispiness.
