Crispy Mushroom & Gruyère Skillet Hash with Dippy Eggs
Tuesday nights call for comfort, and nothing beats my Crispy Mushroom & Gruyère Skillet Hash. This recipe was born out of a very tired brain and a fridge holding only a lonely pack of cremini mushrooms, some leftover boiled potatoes, and a fancy wedge of Gruyère I bought on a whim. I threw them all into a blazing hot skillet, crossed my fingers, and created pure magic. What makes this special to you—and to me—is that it feels luxurious without any fuss. The earthy mushrooms get deeply browned, the cheese gets all melty and crisp at the edges, and those dippy fried eggs on top act as the absolute best sauce. Yes, you can swap the Gruyère for cheddar if that is what you have, and no, you do not need to chop the potatoes small if you are in a rush. Just smash them and let the pan do the work. Delicious really does not have to be difficult, and this skillet proves it every single time.

- 1/2 tsp smoked paprika
- 1 tsp kosher salt(Divided to taste)
- 1/2 tsp black pepper(Freshly cracked, divided)

Instructions
- 1
Place 1 lb baby Yukon gold potatoes, quartered in a microwave-safe bowl with a splash of water. Cover with a plate or damp paper towel and microwave on high for 4 minutes until just fork-tender. Drain well and pat thoroughly dry with a paper towel.
5 min
Tip: Pre-steaming in the microwave is my favorite weeknight hack—you get that roasted potato texture in a fraction of the time without boiling a big pot of water.

While the potatoes steam, heat a large (12-inch) cast-iron or heavy skillet over medium-high heat. Add 1 tbsp extra-virgin olive oil and 1 tbsp unsalted butter. Once sizzling, add 12 oz cremini mushrooms, wiped clean and halved cut-side down in a single layer. Let them sear completely undisturbed for 4 minutes until deeply browned, then toss and sear for another 2 minutes. Season with 1/2 tsp kosher salt and 1/4 tsp black pepper.
6 min
Tip: Do not touch them for the first 4 minutes! Crowding or stirring immediately traps moisture and steams mushrooms instead of caramelizing them.

Push the mushrooms to the perimeter of the skillet. Add the remaining 1 tbsp extra-virgin olive oil to the center, followed by the par-cooked potatoes. Spread them flat and cook undisturbed for 4 minutes until golden and crusty on the bottoms. Stir together with the mushrooms, then add 2 medium shallots, thinly sliced, 3 cloves garlic, minced, 1 tbsp fresh thyme leaves, 1/2 tsp smoked paprika, 1 tsp Dijon mustard, and remaining 1/2 tsp kosher salt and 1/4 tsp black pepper. Sauté together for 3 minutes until the shallots soften and become fragrant.
7 min
Tip: The Dijon acts like an instant pan sauce emulsifier, lending rich savory depth that cuts right through the earthy mushrooms.
- 4
Sprinkle 1 cup shredded Gruyère cheese evenly across the hot hash. Use the back of a spoon to create 4 small wells in the mixture, dropping a dab of the remaining 1 tbsp unsalted butter into the bottom of each well. Crack 4 large eggs directly into the indentations.
2 min
Tip: Creating little nests keeps the whites contained so they cook evenly without running all over the edges.
- 5
Cover the skillet with a lid or baking sheet, reduce heat to medium-low, and cook for 3 to 4 minutes until the whites are just set and the yolks are still runny and dippy. Remove from heat immediately, garnish with 2 tbsp fresh chives, finely chopped, and serve warm straight from the pan.
4 min
Tip: Keep an eye on the eggs in the last minute—residual heat in a cast-iron pan will continue to cook them even after you pull it off the burner.
Chef's Notes
Breakfast for dinner is my ultimate fallback when 6 PM hits and I want something deeply comforting without facing a mountain of dishes. The secret to this dish is letting the mushrooms brown undisturbed before salting—salt draws out water, so seasoning them at the end guarantees deeply browned, savory edges rather than a watery skillet. If you want a bit of heat, throw a pinch of crushed red pepper flakes in with the garlic!

Delicious doesn't have to be difficult
I spent a decade in restaurant kitchens before my daughter was born and I realized I needed a different relationship with food. The 16-hour days had to end, but my love of cooking didn't. Now I'm obsessed with the puzzle of making genuinely good food achievable on a Tuesday night. No weird ingredients, no 47-step processes—just smart techniques and bold flavors that come together fast. Because life is too short for boring weeknight dinners.
