Ready In:




  • Preheat oven to 400 deg F.
  • Coat a large, shallow baking dish with cooking spray or oil. The dish should be large enough to hold the onion halves.
  • Trim about 1/4 inch off top and bottom of the onions, so that the halves will sit flat. Cut the onions in half crosswise and then peel them. Arrange the halves, middle cut side up, in the baking dish.
  • Brush the exposed onion tops with olive oil and sprinkle with salt and pepper. Bake about 35 minutes.
  • In a glass measuring cup, combine the broth and soy sauce.
  • Remove the onions from the oven, pour the broth mixture over the onions.
  • Return the baking dish to the oven, and bake an hour longer, basting from time to time. If the sauce gets very low, add some water.
  • Remove the dish from the oven and sprinkle evenly with the cheese and chopped sage. Bake 5 to 7 minutes longer, or until the cheese melts.

    Excellent recipe...we've made it several times - it is SOOO good. <br/><br/>However, last night, I found out the hard way that I shouldn't use Pyrex for a baking dish...As I was adding the beef broth, it exploded...Glass shrapnel EVERYWHERE! Very scary. I should have known better...DO NOT USE PYREX for this recipe!

    Yes this does look and taste like just like Morton's. We really liked all that yummy baked gruyere on top. This is a recipe were you want to use a good quality beef broth. Like the way you have the onions cut as doing so makes them hold together nicely and the basting ensures that the beef flavor is infused into all layers of the onion, yum. Thank you for the post.

    This was just delicious! Definately going into my keeper cookbook. I did scale the recipe down for one onion and used homemade vegetable broth. Made for the 123 Hit Wonder game.


My screen name is a diminutive in Lithuanian for bread, so you won't be suprised to learn that I love to bake bread. In recent years I have been baking a lot of sourdough breads and have several starters sitting in my refrigerator. But I like to cook a lot of other things, as well, especially from various cultures. The cat wishes I would concentrate on meat and fish... I joined a few years ago but started posting recipes and participating in forums just recently - I wish I had done so earlier. Recipezaar is a great community! Right now I am a co-host for the Breads and Baking and the Eastern Europe forums - I hope to see you there!
