Sunny side up eggs are a breakfast classic: a fried egg cooked gently on one side until the white is set and the yolk remains glossy and runny. The name comes from the yolk’s resemblance to a sun, and the technique is simple, but nailing the texture—tender white, crisp lacy edges, and a warm liquid yolk—requires a bit of finesse. This method uses low heat and a covered pan to set the white without flipping, giving you a reliable, beautiful result every time.
Ingredients
- 1 large egg (about 50 g, out of shell)
- 1 teaspoon (5 ml) unsalted butter or olive oil
- Kosher salt and freshly ground black pepper, to taste
Instructions
- Heat a small nonstick skillet over medium-low heat for 1 minute. Add the butter or oil and swirl to coat the bottom. The fat should shimmer but not smoke.
- Crack the egg into a small bowl, then gently slide it into the center of the skillet. If you prefer a perfectly round egg, you can use a ring mold or simply let it spread naturally.
- Cook undisturbed for 2 to 3 minutes, until the white is mostly set but the yolk is still soft. The edges should be lightly golden and crisp.
- If the white around the yolk is still translucent, cover the pan with a lid for the last 30 seconds to 1 minute. The trapped steam will set the white without cooking the yolk. Do not flip the egg.
- Slide the egg onto a plate. Season with salt and pepper immediately, while the surface is still slightly moist, so the seasoning adheres. Serve hot.
Tips
- Use fresh eggs: Fresher eggs have thicker whites that hold their shape better, giving a neater appearance. Older eggs spread thin and can make the white watery.
- Low and slow: High heat causes the white to brown too quickly and the yolk to overcook. Medium-low ensures a tender white and a runny yolk.
- Butter vs. oil: Butter adds flavor and helps create crisp edges, but it can brown if too hot. Olive oil gives a cleaner, more neutral taste and a slightly crisper edge. Use clarified butter or a neutral oil if you prefer no dairy.
- No lid? Baste: If you don’t have a lid, spoon a little hot butter or oil over the white (not the yolk) to help it set. This is the classic French basting method.
Serving Suggestions
Serve sunny side up eggs on toast, alongside crispy bacon or sausages, over rice and beans, or on top of a grain bowl. They also make a great topping for burgers, avocado toast, or a hearty salad. For a classic American breakfast, pair with hash browns and a cup of coffee.
Variations
- Over easy: Flip the egg and cook for 15–20 seconds on the second side for a slightly set white with a runny yolk.
- Over medium: Flip and cook for 30–45 seconds for a yolk that is partially set but still soft.
- Over hard: Flip and cook for 1 minute or until the yolk is fully cooked.
- Spicy: Add a pinch of chili flakes, smoked paprika, or a dash of hot sauce before serving.
- Herbed: Sprinkle with chopped chives, parsley, or dill after cooking.
- Cheese: Grate a little Parmesan or cheddar over the egg during the last minute of cooking, then cover to melt.
Storage and Reheating
Sunny side up eggs are best eaten immediately. If you have leftovers, refrigerate them within 2 hours in an airtight container; they will keep for up to 2 days. To reheat, place the egg in a skillet over low heat with a splash of water and cover for 1–2 minutes, or microwave on a plate for 20–30 seconds. Note that the yolk will become firm upon reheating, and the texture will not be as delicate.
Frequently Asked Questions
Why is my egg white runny around the yolk? This happens when the white is not fully set. Covering the pan with a lid for a short time traps steam that cooks the white gently without overcooking the yolk. Also, make sure the pan is not too hot, which can cook the outside while leaving the center underdone.
Can I use a regular (nonstick) pan? Yes, but you’ll need more fat and careful heat control. A well-seasoned cast iron or stainless steel pan works, but a nonstick pan makes it easiest to slide the egg out without breaking the yolk.
How do I get crispy edges? Use a generous amount of fat (about 1 tablespoon) and cook over medium-high heat for the first minute, then reduce to medium-low. The fat will fry the edges, creating a lacy, golden rim.
Is it safe to eat runny yolks? The USDA recommends cooking eggs until both the yolk and white are firm to reduce the risk of Salmonella. If you prefer runny yolks, use pasteurized eggs, which have been heated to kill bacteria, and avoid serving them to pregnant people, young children, older adults, or anyone with a weakened immune system.
Can I make sunny side up eggs in the oven? Yes, crack eggs into a greased muffin tin or small baking dish and bake at 350°F (175°C) for 8–10 minutes, until the whites are set but the yolks are still soft. This is great for cooking multiple eggs at once.
Why does my egg stick to the pan? The pan may not be hot enough, or there isn’t enough fat. Heat the pan, add fat, and let it melt before adding the egg. Also, use a spatula to gently loosen the edges before sliding out.
