Prosciutto-Wrapped Portobello Mushrooms with Baked Eggs

It is cold here right now.

I often have to defend New Jersey’s weather to friends and family in Texas. Most of the time I explain that the state enjoys four pleasant, distinct seasons: springs full of blooming flowers, comfortable sunny summers, crisp autumns with colorful leaves and apple orchards. But winter is another story.

Our winters aren’t the snowiest in the country, and average temperatures are milder than in many places, but my Texas-born blood hasn’t fully adapted. This week has been particularly harsh with single-digit temperatures and wind chills below zero. I miss the sight of hyacinths and daffodils poking through the soil — a promise of warmer days ahead.

Yesterday we made a quick trip to a local farm to stock up on meat and eggs. The farm store was unheated, and the only heater barely made a difference. Ironically, the refrigerated cases kept the fresh eggs warmer than the rest of the building. We grabbed grass-fed brisket, homemade pork breakfast sausage, ground venison and farm-fresh eggs and hurried back home. (A shout-out to Ugg boots for improving winter life considerably.)

Back at home I decided to bake some eggs in portobello mushroom caps — an easy, tasty breakfast that’s paleo-friendly and low in carbs. If you haven’t tried it before, know that the egg can sometimes slide off depending on the mushroom’s shape, so handle them carefully. Here’s a clear, simple version of the recipe I made.

Baked Eggs in Portobello Mushroom Caps

Ingredients

  • Farm-fresh eggs
  • Portobello mushroom caps
  • Slices of prosciutto
  • Black pepper
  • Fresh parsley or thyme
  • A little olive oil

Instructions

  1. Clean each portobello cap with a damp cloth. Remove the stem and scrape out the gills so you have a cavity deep enough for an egg.
  2. Lightly rub olive oil on the outside of each mushroom to help it cook evenly and prevent sticking. Arrange the caps on a baking sheet, gill-side up.
  3. Place one slice of prosciutto into the cavity of each mushroom cap.
  4. Crack an egg into a small bowl, then carefully slide the egg onto the prosciutto-lined mushroom cap to avoid spills.
  5. Season with black pepper and sprinkle with fresh parsley or thyme. Because prosciutto is already salty, extra salt is usually unnecessary.
  6. Preheat the oven to 375°F (190°C). Carefully place the baking sheet in the oven and bake for 20–30 minutes, depending on mushroom thickness and how set you like your eggs. Check after 20 minutes and adjust the time to reach your preferred doneness.

This dish is simple, nourishing and satisfying — perfect for chilly mornings when you want something warm and hearty without a lot of fuss. The mushrooms provide a savory base, the prosciutto adds a salty, meaty bite, and the baked egg ties everything together into a single, elegant serving.

  • Total Time: 30–40 mins
  • Yield: Varies (depends on number and size of mushrooms)
  • Category: Breakfast
  • Cuisine: Paleo

Tips for success:

  • Choose portobellos with a relatively flat, deep cap so the egg sits securely.
  • If a cap is shallow or oddly angled, try trimming the underside slightly to level it, or nestle it against another cap on the pan for stability.
  • Cracking the egg into a small bowl first helps you slide it gently into place and keeps shells out of the mushroom.
  • Check eggs toward the end of cooking so you can pull them when the whites are set but the yolks are still runny if you prefer.

Here’s hoping your eggs stay snugly in their mushroom caps and that you stay warm through the winter. This is a great little recipe to make when you want something comforting, flavorful and quick. Enjoy!
