Ingredients for Open-Faced Mushroom and Fried Egg Sandwiches on a sheet pan. Ingredients include bread slices, sauteed mushrooms, shallots, parmesan cheese, pesto and sliced bread. What the heck is an open-faced sandwich?

If you’re traveling to France, you’ll often see open-faced sandwiches referred to as tartines, which translates to “slices of bread”. An open-faced sandwich is simply a piece of bread or toast that is piled high with toppings.

Serving your sammies open-faced allows the ingredients to shine rather than be hidden or overshadowed by another slice of bread. All those tasty toppings also means that open-faced sandwiches should be savored with a knife and fork rather than eaten on the run.

Do I have to use a certain bread for this fried egg sandwich?

No bread rules here other than pick something sturdy that can stand up to the toppings. Slices from an artisan loaf like sourdough or rye bread are perfect for this open-faced sandwich. Softer sandwich bread just won’t cut it here.

Ah, this is my favorite part. All the delicious toppings.

While the list of ingredients for this Open-Faced Mushroom and Fried Egg Sandwich sounds lengthy, it comes together rather quickly, and the sum of the parts is truly amazing.

I’m talking hearty cremini mushrooms, bright basil pesto, juicy tomato slices, crispy shallots and salty parmesan all topped with a perfectly fried egg.

I like my egg a little runny so the yolk drips down the side of the sandwich, but cook the egg to your own preference. Heck, you could even scramble an egg and layer it on top. No rules here, just deliciousness.

Prep Time 15 minutes
Cook Time 30 minutes
Total Time 45 minutes


  • 4 teaspoons extra-virgin olive oil, divided
  • 1 cup thinly sliced shallots, divided
  • 1 1/2 packages presliced cremini mushrooms (12 ounces total)
  • 2 tablespoons dry white wine or chicken broth
  • 1/2 teaspoon freshly ground black pepper, divided
  • 1/4 teaspoon kosher salt
  • 8 teaspoons refrigerated pesto
  • 4 slices crusty artisan bread (such as sourdough, pumpernickel, etc.)
  • 1/2 cup grated fresh Parmigiano-Reggiano cheese
  • 4 large eggs
  • 8 slices beefsteak tomato
  • 3 tablespoons chopped fresh basil


  1. Heat a large nonstick skillet over medium heat. Add 2 teaspoons oil and 2/3 cup shallots to the pan. Cook for 3 minutes.
  2. Add mushrooms to the pan. Cook for 8-10 minutes or until tender, stirring occasionally.
  3. Add wine, 1/4 teaspoon pepper, and salt to the skillet. Bring mixture to a boil, scraping pan to loosen browned bits. Cook 2 minutes or until liquid almost evaporates, stirring occasionally.
  4. Remove mushroom mixture from pan; keep warm.
  5. Return pan to medium heat. Add 1 teaspoon oil and the remaining 1/3 cup shallots to the pan. Sauté for 5-7 minutes or until browned and almost crispy. Remove shallots from pan; keep warm.
  6. Preheat broiler to high.
  7. Spread 2 teaspoons pesto over one side of each bread slice. Top each slice with about 2 tablespoons cheese. Broil 2 minutes or until cheese melts; keep warm.
  8. Return pan to medium heat. Add remaining 1 teaspoon oil to pan; swirl to coat. Crack eggs into pan, and cook 4 minutes (until whites are set) or to desired level of doneness.
  9. Evenly divide mushrooms among four bread slices. Top each piece of bread with two tomato slices and one cooked egg. Sprinkle bread slices with remaining shallots, ground pepper and chopped basil. Serve immediately.


Short on time? You can make the mushroom mixture and the shallots ahead of time and simply reheat them prior to building the sandwiches.

    I’m such a sucker for a good sunny-side up egg… probably explains why brunch is my favourite meal, with breakfast-for-dinner as a close second. 🙂
    This reminds me a little bit of my favourite menu item at a local brunch place, though they use toasted bagels in lieu of toast (and add crispy bacon, because everything is better with bacon). Must try it out next time I’ve got a breakfast craving at dinnertime!

      Yay! Another breakfast food groupie! Your local brunch spot sounds right up my alley. Another reason to visit Toronto…

    Made this delicious sandwich for my Dad (and the rest of the family too) on Father’s Day!

    It was an absolute hit. We did play around with the recipe a bit – we omitted the salt and added some prosciutto (one of my Dad’s favourite things to eat), and topped it with arugula before adding the tomatoes and egg. It not only looked beautiful, but tasted great. I’ll absolutely be making it again!
    Thanks for the recipe!
