Step-by-Step Instructions

Step 1: Roast the garlic

Preheat the oven to 400°F (204°C). Remove the loose papery layers from the garlic while keeping the head intact. Slice about 1/4 inch from the top to expose the cloves. Place the garlic cut-side up on a piece of aluminum foil, drizzle it with 1 teaspoon olive oil, and wrap the foil tightly around it. Roast for 40 minutes, until the cloves are golden, very soft, and easily pierced with a small knife. Open the foil carefully and let the garlic cool for 5 minutes.

Step 2: Start the polenta

When the garlic has been roasting for 10 minutes, combine 3 cups water, 1 cup whole milk, and 1/2 teaspoon kosher salt in a heavy-bottomed medium saucepan. Bring the mixture to a gentle boil over medium-high heat, stirring occasionally so the milk does not scorch. Reduce the heat to low. While whisking constantly, pour in the polenta in a thin, steady stream to prevent lumps.

Cook the polenta over low heat for 30 minutes, keeping it at a gentle bubble and whisking thoroughly every 5 minutes. Take care when uncovering or stirring because thick polenta can splatter. If it becomes stiff before it is tender, whisk in additional hot water 2 tablespoons at a time, using no more than 1/2 cup.

Step 3: Finish the roasted garlic polenta

Squeeze the softened roasted garlic cloves from their skins into a small bowl and mash them into a smooth paste with a fork. When the polenta is tender and creamy, stir in the roasted garlic paste, 2 tablespoons unsalted butter, and 3/4 cup Parmesan. Whisk for 1 minute, until the butter and cheese are fully melted. Remove the pan from the heat, cover it, and keep it warm. The finished polenta should be soft enough to settle slowly when spooned into a bowl; whisk in a splash of hot water if it thickens while standing.

Step 4: Sauté the mushrooms and wilt the spinach

While the polenta cooks, heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat. When the butter begins to foam, add the sliced mushrooms in an even layer. Leave them undisturbed for 3 minutes so the first side can brown. Continue cooking for 5 minutes, stirring only occasionally, until the mushrooms are deeply browned and their released liquid has evaporated.

Add 2 teaspoons thyme leaves, 1/4 teaspoon kosher salt, and 1/4 teaspoon black pepper. Stir for 30 seconds. Add the spinach in two or three handfuls, tossing after each addition. Cook for 2 minutes, just until the spinach is wilted but still bright green. Reduce the heat to its lowest setting while you poach the eggs.

Step 5: Poach the eggs

Fill a wide saucepan with 3 inches of water and heat it to 185°F (85°C). The water should show gentle movement and a few small bubbles but should not reach a rolling boil. Add 1 tablespoon distilled white vinegar. Crack 4 eggs into separate small bowls or ramekins, taking care not to break the yolks.

Lower each egg gently into the water, spacing them apart. Poach for exactly 3 minutes 30 seconds for set whites and warm, runny yolks. Lift each egg out with a slotted spoon and place it briefly on a clean kitchen towel to remove excess water. Return the water to 185°F and repeat with the remaining 4 eggs.

Step 6: Assemble and serve

Whisk the warm polenta once more, adding 1 to 2 tablespoons hot water if needed to restore its creamy texture. Divide the polenta among 4 shallow bowls. Spoon equal portions of the mushrooms and spinach over the polenta, then place 2 poached eggs on each serving. Finish with the remaining 1/4 cup Parmesan, 1 teaspoon thyme leaves, and 1/4 teaspoon black pepper. Serve immediately so the polenta stays creamy and the egg yolks remain warm and fluid.

Pro Tips

Choose the right polenta: Coarse stone-ground polenta develops the best corn flavor and creamy texture. Instant polenta cooks too quickly for the timing in this recipe.
Use fresh eggs: Fresh egg whites hold closely around the yolks, producing neater poached eggs with fewer wispy strands.
Give the mushrooms room: A 12-inch skillet allows moisture to evaporate so the mushrooms brown instead of steam. If your skillet is smaller, cook them in two batches.
Keep the polenta loose: Polenta thickens quickly as it stands. Whisk in hot water 1 tablespoon at a time just before serving.
Watch the poaching temperature: Boiling water can tear the egg whites, while water below 180°F may not set them properly. Aim for a steady 185°F.

Variations

Truffle mushroom polenta: Stir 1 teaspoon truffle oil into the finished mushrooms immediately before serving.
Goat cheese polenta: Replace 1/2 cup of the Parmesan in the polenta with 3 ounces soft goat cheese for a tangier, creamier finish.
Hearty greens: Replace the baby spinach with 5 ounces thinly sliced lacinato kale. Add 2 tablespoons water and cook the kale for 5 minutes, until tender.

Storage & Make-Ahead

Refrigerate leftover polenta and the mushroom-spinach mixture in separate airtight containers for up to 3 days. Reheat the polenta in a saucepan over low heat with 2 to 4 tablespoons milk or water per serving, whisking until smooth. Reheat the vegetables in a covered skillet over medium-low heat for 3 to 4 minutes. For make-ahead poached eggs, cook them as directed, immediately transfer them to ice water, and refrigerate them submerged in fresh cold water for up to 24 hours. Reheat the eggs in 160°F (71°C) water for 1 minute before serving. Do not freeze the assembled dish, as the eggs and polenta will lose their best textures.
