The Best Croutons and How Best to Eat Them


Fernand came to the café where I waitressed in sunny CA every Sunday afternoon for the same meal: an omelet, a baguette, and a side of Dijon mustard. He ate his omelet methodically, spreading mustard over each slice of bread first, spooning bits of his creamy eggs overtop next. A mustard-slicked slice of bread accompanied every bite of omelet.

I always thought this mustard routine was a little odd. Slatherings of butter, cheese, and jam made sense to me. Mustard felt foreign. But when I read the description in The Zuni Cafe Cookbook of Madeleine’s omelet, and more specifically of the croutons that lace that omelet, I wondered if Fernand, or the French, were on to something.

Before we get to the croutons, a little background might be helpful: Madeleine is the sister of Jean and Pierre Troisgros, the brothers who ran the restaurant Les Frères Troisgros in Roanne, where Judy Rogers spent a year as a young teenager watching, tasting and recording everything that she could. During this year, too, at least twice a week, Rogers would escape to Madeleine’s home kitchen and delight in dinners of scrambled eggs filled with nutty hard cheeses and croutons or with lightly browned potatoes and bacon.

Given the generous amount of Dijon mustard and mustard seeds that dress Madeleine’s croutons, I suspect Fernand would approve of them wholeheartedly. And finding them in an omelet might just send him over the moon. Golden on the outside, chewy on the inside, mustardy throughout, these croutons are irresistible. And while they certainly are not as hard core as straight up mustard bruschetta, I should have known better than to question the eating habits of a French wine purveyor from Burgundy.

So, what’s the best way to eat these little nuggets? Well, perhaps we should start with how you shouldn’t eat them, which is how I ate them this afternoon for lunch, which is popcorn style, bowl in lap while gazing out the window, popping down one after another. This was a treat, therapeutic even as my children were nowhere in sight, but perhaps not recommended. A salad is an obvious and good option (I did save a few for this purpose), but I suspect their best home is in the center of an omelet, Madeleine style, surrounded by some sort of melty Gruyère-type cheese. I think the French are in fact on to something with this bread-mustard-egg combo. Perhaps something to ponder this weekend. Maybe over dinner this evening?

Mustard Croutons

Source: The Zuni Cafe Cookbook

stale, chewy, peasant-style bread, most of the crust removed*
2 tablespoons unsalted butter
1 tablespoon Dijon mustard
1.5 tablespoon dry white wine or dry white vermouth (I used the vermouth)
1 teaspoon mustard seeds, lightly crushed in a mortar
freshly ground black pepper
kosher salt to taste

* Recipe suggests 2.5 oz, but I think you’ll need a little more. I weighed my 2.5 cups of crustless cubed bread, and it weighed more like 7 oz. I know all breads are different, and mine likely is a little denser than what Zuni was using. Also, I used more like 3 cups of cubed bread.

1. Preheat the oven to 400° F.

2. Tear the bread into small, fluffy wads, about 3/4 inch and smaller. Tear a few of the wads into crumbs. You should get 2 to 3 cups.

3. Melt the butter in a small saucepan or skillet, then remove from heat and whisk in the mustard, wine, seeds, and lots of black pepper. The mixture should be the texture of a thick vinaigrette. Add the bread and toss well to coat. (I did this in a large bowl, but if your saucepan is large enough to hold all the cubes, just go ahead and add the bread directly to the pot.) Rub the bits of bread against the sides of the pan to grab all the dressing, then massage them gently to make sure the dressing reaches the inside of the wads. (I didn’t really do all of this — just gave them a nice toss, but feel free to massage as you wish.) Taste for salt. (I didn’t add any more salt.)

4. Spread the bits of bread out on a sheet pan and toast for 5 to 10 minutes (or longer), until unevenly golden on the outside but still slightly chewy in the middle. The smaller crumbs will be crisp through. Toss into a salad, or if adding to an omelet, keep the croutons in a warm spot.

    Wow this sounds good. I usually just toss my pieces of bread in olive oil and a few spices and bake low and slow to dry them out for longer storage. This sounds and looks so good I have to try it. Thanks for the idea.

    Another recipe using lots of mustard (and this time no curry powder yay!), I don’t usually do croutons at home but this sounds excepting…esp the use of it inside an omelette. If only I had some bread in the house now it would be perfect for breakfast this morning.

    Explody Full — I thought of you immediately (obviously) when I spotted the EXCELLENT amount of mustard and mustard seeds in the recipe. These are SO good. Try them!

  4. says

    Gracious! These sound absolutely perfect. I’m eating my packed-for-the-office lunch right now — slivers of beets, quinoa and ribbons of raw collard leaves — I can’t imagine a better compliment for my salad than these chewy, crisp and mustardy croutons. I’m trying them this week! Thank you!

      Sophie — you are most welcome! And your lunch sounds amazing — so healthy and delicious. I have been experimenting with quinoa recently. Do you cook with it often? Do you have any tips?

  5. says

    I do cook it once or twice a week, so that there is always a supply in the fridge. I usually eat it with all my lunches, tossed with any fresh veggies or greens, for an inexpensive boost of protein and texture. I also tried it toasted over Greek yogurt with honey and walnuts… great breakfast! The tips I’ve learned are to give it a good few initial rinsings (to remove any bitterness), as I’m sure you know, and to cook it like pasta, in lots of extra water, and to drain when done. This helps me since the amount of water it will absorb during cooking seems to vary depending on brand/batch/freshness.

    I’ve got my bread and mustard seeds on hand for these croutons tonite! And congratultions on your post at Cup o Joe! Very exciting to see your familiar photography there! :)

      Sophie — thanks so much for your response here! I spotted a recipe for breakfast quinoa in Bon Appetit and have been meaning to try that. Great tip about the extra water. I have been wondering about that. I had read that the rinsing was important, but I have heard various things about how much water to use, and I like the idea of cooking it in lots of excess water and letting it drain when it’s done.

      And I hope you like those croutons! They are heaven to me :)
