Why It Works
- Caramelizing the onions builds deep, candy flavors.
- Deglazing the onions with dry sherry mimics the sherry or calvados you’d use in French onion soup.
- Gruyère is melted into the silky cheese sauce and folded into the mac and cheese in cubes for melty, stretchy bites.
- Including beef bouillon paste and Dijon mustard to the cheese sauce balances the sweetness of the caramelized onions and mimics French onion soup’s beef broth base.
We’re firmly within the age of the culinary mashup, and it is pleasant. Bulgogi burritos, ramen burgers, smash burger quesadillas, totchos, Caesared spaghetti, purple velvet brownies, and now: French onion soup mac and cheese. After all, mashups can go flawed (taking a look at you, rooster noodle soup cough drops), however within the case of this pasta dish, every little thing could be very, very proper. We begin with all-American mac and cheese—which is actually comforting however frankly could be a baby dimensional—and zhuzh it up with all the trimmings of French onion soup, together with buttery caramelized onions, nutty Gruyère, and a crunchy breadcrumb topping.
Whereas the flavors of mac and cheese are usually fairly simple, this recipe, developed by our Birmingham-based check kitchen colleague Julia Levy, is layered with deep, wealthy flavors. As quickly as you set your water to boil for the pasta, you may start caramelizing onions—a full pound and a half of them. To hurry the cooking admittedly prolonged time it takes to caramelize the onions, Julia has you begin by protecting the lid to start with, then eradicating it to proceed cooking till the onions are very mushy and brown.
This preliminary step of protecting the pot traps steam, serving to to melt the onions a lot sooner than if the lid is left off. As quickly as they’re softened, the lid comes off to let that steam escape and the browning start. Even with this shortcut, the onions will take about 40 minutes to succeed in the candy taste and almost-melting consistency we’re in search of. Do not lower the cooking time quick—these onions are the star of the present. The excellent news is that the onions solely should be stirred sometimes, so you’ll be able to multitask and grate and dice the cheese whereas the onions prepare dinner. As soon as the onions are browned, dry sherry and aromatic contemporary thyme go into the pot to additional construct these traditional French onion soup flavors.
The cheese sauce is a traditional mornay sauce made with a butter-and-flour roux, milk, and cheese, however there is a intelligent addition to provide the dish the beefy taste of French onion soup: bouillon paste, resembling Higher Than Bouillon. Bouillon paste provides a concentrated kick of savory beefy taste with out diluting or thinning the sauce the best way inventory or broth would (plus, we expect it might be a bit a lot to make do-it-yourself beef inventory only for a mac and cheese, and we usually discover that store-bought beef broth tastes horrible).
After all cheese is a key element of each mac and cheese and French onion soup, and right here we’re utilizing the traditional French onion topper, Gruyère. Julia examined utilizing a mix of Gruyère and onion Jack, however in the end determined it was greatest to simply let the Gruyère shine by itself. It is a fantastic melter, so there is no want so as to add different cheeses for the requisite creaminess and gooeyness of mac. Along with melting Gruyère into the sauce, the recipe additionally requires folding cubes of the cheese into the mac and cheese combination earlier than baking to create little pockets of melty, stretchy cheese all through.
The ultimate contact is our nod to the croutons that go on French onion soup: panko breadcrumbs combined with store-bought crispy fried onions. Then into the oven it goes to bake till bubbly, browned, and crispy on high. This baked mac is substantial sufficient to serve by itself or with a easy inexperienced salad, but it surely additionally pairs nicely with roasted or fried rooster and makes a fantastic centerpiece for a vegetarian plate. Oooh-oui it is good!
