Preheat oven to 375 degrees F. with rack in center. Heat olive oil in a 10 inch cast-iron skillet over medium-high heat. When oil is shimmering, add onion and bell pepper and sauté until beginning to soften, about 5 minutes. Remove pan from heat and add marinara sauce and artichoke hearts. Crack eggs into sauce and sprinkle with generous pinches of salt and pepper. Sprinkle crumbled feta or goat cheese over pan. Transfer pan to oven and bake until egg whites are set but yolks are still slightly runny, 15 to 20 minutes. Scatter parsley over top before serving warm from skillet, family-style.: As the kitchen warms, you will notice a faint rise in ambient heat, and that preheated oven ensures the eggs set evenly without overcooking. The oven’s steady warmth gives a gentle, enveloping heat that cooks the whites through while leaving yolks glossy. Avoid starting with a cold oven, which can lead to inconsistent cooking and rubbery whites.
Heat olive oil in a 10 inch cast iron skillet over medium high heat: The oil should shimmer and move easily in the pan, releasing a light fruity scent when ready. Heating in a cast iron skillet gives an even base and helps maintain temperature when you transfer to the oven, producing gentle, even heat around the sauce. If the oil smokes, lower the heat immediately to prevent off flavors.
When oil is shimmering add onion and bell pepper and sauté until beginning to soften about 5 minutes: You will hear soft sizzling, and the onion will turn translucent while the bell pepper loses some firmness. The sound becomes a gentle whisper rather than a roar, indicating the vegetables are sweetening. A common error is rushing this step on too high heat which causes uneven browning instead of gentle softening.
Remove pan from heat and add marinara sauce and artichoke hearts: The cool-down of the pan before adding the jarred sauce prevents splattering and keeps the oil from overheating. As you stir, the sauce will blend, and the artichoke hearts will nestle into the tomato base, releasing a faint briny note. If you add sauce to a searing pan it may sputter and reduce too quickly, altering the sauce texture.
Crack eggs into sauce and sprinkle with generous pinches of salt and pepper: The moment you crack the eggs into wells in the sauce, you will see bright yolks shining against the crimson backdrop. The salt and black pepper draw out flavor and help the eggs set with a seasoned edge. Be careful not to crowd the pan so each egg has room to cook evenly, otherwise some will finish sooner than others.
Sprinkle crumbled feta or goat cheese over pan: As the cheese hits the warm sauce it will begin to soften and form creamy pockets that contrast with the smooth yolks. The aroma becomes tangier and more layered, signaling the marriage of flavors. Overdoing the cheese can mask the delicate artichoke notes, so keep a balanced hand.
Transfer pan to oven and bake until egg whites are set but yolks are still slightly runny 15 to 20 minutes: Inside the oven you will hear a gentle hum rather than active sizzling, and visually the whites will firm into opaque ribbons while the yolks remain glossy. This timing yields silky yolks that break into the sauce and create a luxurious mouthfeel. Opening the oven too soon or leaving it too long risks underdone whites or firm yolks, so check visually toward the end of the bake time.
Scatter parsley over top before serving warm from skillet family style: The fresh parsley adds a flash of green and a clean herbal brightness that lifts the dish as soon as it comes out of the oven. Serve directly from the skillet so everyone can dig in while it is still bubbling slightly around the edges. If you wait too long to serve, the dish will settle and lose some of its inviting steam and warm aroma.
