This is the first of two onion recipes I’m going to share. Tomorrow you’ll learn more about how/why I have these wonderful sweet onions in the first place, but will post this one first. You’d likely think the above bruschetta was topped with an olive tapenade. Nope. Or maybe a fig jam? Nope. Could even be dark mushrooms? No on all counts. It’s onions.
We went out to dinner last night with good friends, and our custom with Bob & Liz is to gather at one or the other of our homes for some pre-prandial appetizers and wine, then off we go to a restaurant. We’ve been trying to go to NEW restaurants every time we go out, so it keeps us on our toes to find new ones to try. We’ve been very successful so far, even in this economy!
I’d made this appetizer a few days ago with the first of my big onion bonanza and we polished it off last night with our wine and food before dinner. Liz wants the recipe. I’ll be making these again soon.
So here’s the story about them. The recipe is based on one from a new cookbook called The New American Olive Oil, by Fran Gage. I followed her recipe mostly, but then I took a right turn and made it different. After trying it once according to the recipe, I made it my own with the garnish. First you slice about 2 pounds of onions (I used sweet onions) and sauté them with about 4 T. of extra-virgin olive oil and a tiny smattering of salt. It cooks. And cooks. And cooks. At a very low heat for about an hour. You stir occasionally, and more often near the end so the onions don’t stick. During the hour of cooking they lose all their water and they cook down and down and down. The recipe suggests cooking them until they are the color of a polished mahogany table. Am sure you can get the picture. When mine were looking like the skin of an Idaho potato I knew I still had room to go. But stirring is required from then on. Still on fairly low heat. And finally, it DID get to be the color of mahogany.
The huge – HUGE – pan of onions had dwindled to about a half a CUP of dark brown goop. After cooling, you add in some GOOD balsamic vinegar (I happened to use pomegranate balsamic vinegar because it sits out on my countertop). Then you taste it for seasoning. Toasted bread is in order (baguette slices, spread lightly with olive oil and baked at 400 for about 4-5 minutes), then you gently spread some of this heaven-on-a-bun on top of the toast pieces. Here’s where I took the right turn. I thought it needed a taste-foil, so I added some boursin cheese crumbles (my recipe below indicates some crumbled goat cheese, either one) and a smattering of finely minced parsley. Then a jot of freshly ground black pepper and it’s ready to serve.
I like this served slightly warm, but it’s up to you. Certainly no colder than room temp, so if you make this ahead, let it sit out a bit, or heat briefly in the microwave before spreading. Just be prepared for a very small SMALL quantity. Two pounds of onions made about 1/2 cup of finished onions. Just so you know . . .

Mahogany Sweet Onion Bruschetta
Recipe: Adapted from a recipe by Fran Gage, The New American
Olive Oil (a cookbook), 2009
Servings: 4
NOTES: Preferably use a baguette for this, and there will be enough onion for about 12-18 slices, probably. You’ll be shocked, really, at how little onions are left for the end product. So don’t plan on 2 pounds of onions serving a crowd. It won’t. The cheese was my addition.
ONIONS:
4 tablespoons extra virgin olive oil
2 pounds sweet onions — peeled, halved, thinly sliced
About 1-2 teaspoons good quality balsamic vinegar, added after they’re cooled [I used pomegranate balsamic, either one is fine]
TOASTED BREAD:
4 slices bread — grilled or toasted in 400 oven until golden
2 tablespoons extra virgin olive oil
Fleur de sel and freshly ground black pepper to taste
1 ounce goat cheese — or Boursin, crumbled [my addition]
4 tablespoons Italian parsley — finely minced
1. Heat the oil in a large skillet (large enough to hold all the onions) over high heat until the oil begins to tremble and fully coats the bottom of the pan. Add the onions, stir to coat the onions, then turn the heat to very low. Sprinkle the onions with a little tiny bit of sea salt. Don’t use much salt because the onions are going to cook down to less than a cup. Cook the onions – uncovered – stirring occasionally (making sure they don’t start to burn), until they are the color of a polished mahogany table. As it gets to the end, you’ll need to stir it much more frequently to prevent the onions from scorching. This will take about an hour. The onions will shrink to next to nothing!
2. Transfer the onions to a bowl and let them cool. Add the vinegar, drop by drop, and taste until the flavor is complex. Sprinkle with more fleur de sel if desired.
3. Brush the bread with 2 T. of oil and put a small mound of onions on each slice. Top with a few crumbles of goat cheese and parsley. Add a few grindings of fresh pepper and serve immediately. I prefer eating this when the onions are warm, so just reheat briefly in the microwave before putting them onto the bread.

Oh gosh, I can almost taste them now! I bet those were the most delicious appetizer! They look wonderful!
These onions were really fabulous. I’m looking forward to making them again, but will make more. 1/2 cup of them as the end result were simply NOT enough! . . . carolyn t
