Spanish Breakfast Casserole with Eggs and Bacon

Preheat oven to 425°. Toss bread and ¼ cup oil on a rimmed baking sheet; season with salt. Toast until croutons are deep brown and crisp, 15–20 minutes. Let cool.

Meanwhile, pulse red peppers, chiles, paprika, and ¼ cup oil in a food processor. Transfer pepper purée to a large bowl; stir in cream and season with salt. Add croutons and toss until evenly coated.

Cook bacon in a large skillet over medium heat, stirring occasionally, until brown and crisp, 4–6 minutes. Using a slotted spoon, transfer bacon to crouton mixture, leaving rendered fat in skillet. Add onion to skillet and cook, stirring, until soft, 7–10 minutes. Add garlic, season with salt, and continue to cook, stirring, until garlic has softened, 1–2 minutes.

Transfer crouton mixture to a 13x9" baking dish, pressing down on bread to submerge in sauce; scatter onion mixture over. Cover with foil and chill at least 2 hours or up to overnight.

Preheat oven to 450°. Bake casserole, uncovered, until top is golden brown, 35–45 minutes. Make 6 wells on surface of casserole with a large spoon and crack eggs into each well; season with salt. Bake again until whites are set but yolks are still runny, 10–12 minutes. Let cool 10 minutes, then top with parsley.
