Tomato Croque Monsieur

Recipe by Kumquat the Cats fr

A delicious vegetarian version that pairs well with inexpensive but good red or white wines. If your tomatoes are not very moist you can omit some of the draining time, like I did. I made this with a processed gruyere cheese (which was all the store had) and Italian flavored bread crumbs. Can be served as canapes (quartered) or makes six sandwiches.

C'est formidable! I LOVED this my lovely catty's friend! I also added some thinly slcied tomatoes to the sandwich for another layer of texture.......and as my basil is not out yet, I added parsley instead of basil. Made for my lunch today and served with a small green salad and yet MORE fresh tomatoes, I LOVE them! A great veggie alternative to the ussual ham croque monsieur - merci! FT:-)

Ingredients Nutrition

  • 2 garlic cloves
  • 2 lbs tomatoes, meaty and ripe, peeled, seeded, juiced and coarsely chopped (dip in boiling water for 30 seconds to peel easily)
  • 12 teaspoon salt (or to taste)
  • 2 tablespoons basil leaves, minced
  • 14 cup dry breadcrumbs
  • fresh ground black pepper, to taste
  • 12 slices white bread (firm, crusts trimmed if desired)
  • 4 -6 ounces gruyere cheese (thinly sliced)
  • 2 teaspoons oil


  1. With a food processor running, drop in garlic until minced. Turn off machine and add tomatoes. Pulse until finely chopped. (This step can also be done manually if preferred, which is how I did it).
  2. Place mixture in a fine sieve over a bowl, stir in salt and allow to drain 30 minutes, pressing down on tomatoes from time to time.
  3. Transfer tomatoes to a bowl and stir in basil and breadcrumbs. Season to taste with salt and pepper.
  4. Arrange half the bread slices on a work surface and spread with tomato mixture. Cover with a thin layer of the cheese and top with remaining bread.
  5. Film a large non-stick skillet with oil. Place as many sandwiches as will fit comfortably and fry over medium-low or medium heat, turning to brown both sides and pressing down lightly with a spatula until golden on both sides. (About 1 1/2 - 2 minutes per side.) Remove to paper towel to drain.
  6. Repeat if necessary while finished sandwiches are kept in a 200 degree Fahrenheit oven to be kept warm. Quarter sandwiches on the diagonal for canapes.
