It fascinating how much variation there can be from one recipe to the next. Three years ago I posted a recipe for Onion Souffle which called for chopped onions, bread crumbs, and egg. The mixture was cooked in individual ramekins. That recipe was good (at least that’s what I wrote at the time), but not memorable. I recently came across another hundred-year-old Onion Souffle recipe that was very different from the other one, so I decided to compare the two recipes. The second recipe called for pureed onion, and was a savory custard.
I can’t tell a lie-
I somehow forgot that I’d previously made an Onion Souffle recipe for this blog until I got ready to write this post. I’d already made the 1921 recipe, and had taken photos of it. When I loaded the photo into my computer and attempted to save it, my computer indicated that I had another photo with the same name. I did a search of A Hundred Years Ago posts for Onion Souffle, and a 2018 post immediately popped up.
Oops! I’d previously done an Onion Souffle post – though I have no memory of it. (It clearly was not a memorable dish).
Who would have guessed that the food I’m inadvertently make twice would be a quirky food like Onion Souffle? Apparently, at some subliminal level, Onion Souffle recipes appeal to me. Strange . . .
In any case, the “new” Onion Souffle recipe turned out well. The savory custard was light and smooth – and had a delightful onion flavor that was just right (and not too strong). I think that this Onion Souffle recipe will be a bit more memorable that the last one.
Here’s the original recipe:

Here’s the recipe updated for modern cooks:
Onion Souffle
6 medium onions
2 tablespoons butter, melted
3 tablespoons flour
1/2 teaspoon salt
3 eggs beaten
1/2 cup hot milk (I heated the milk in the microwave.)
Preheat oven to 350° F. Peel and quarter onions. Put onions in a saucepan, cover with water. Put on stove and bring to a boil Reduce heat and simmer until onions are tender (about 15 minutes). Remove from heat and drain. Puree onions. (I used a Foley mill to puree the onions; though a food processor or blender could also be used.) There should be approximately 1 cup of pureed onion.
In the meantime, combine butter, flour, and salt in a mixing bowl. Add, eggs and beat until smooth. While beating, slowly add the milk. Then add the onion puree and stir quickly to combine. Put in a 1-quart casserole dish. Set the dish in a pan of hot water and place in the oven. Bake 30-45 minutes or until the souffle is set.
