Baked Penne with Farmhouse Cheddar and Leeks

Image may contain Food Bread Plant and Sandwich

An extra-sharp raw-milk cheddar from England is the perfect counterpoint to the sweet sautéed leeks in this upscale twist on mac and cheese.

Ingredients

Makes 6 servings

1/4 cup (1/2 stick) butter
5 cups chopped leeks (white and pale green parts only; about 5 large)
1/4 cup all purpose flour
3 1/2 cups whole milk
1 pound extra-sharp cheddar cheese, coarsely grated (about 4 cups packed)
1 tablespoon Dijon mustard
1 teaspoon hot pepper sauce
2 large eggs
1 pound penne pasta
  1. Step 1

    Lightly butter 15x10x2-inch baking dish. Melt 1/4 cup butter in heavy large saucepan over medium heat. Add leeks; stir to coat. Cover saucepan and cook until leeks are tender, stirring occasionally, about 12 minutes (do not brown). Uncover saucepan; add flour. Stir 2 minutes. Add milk; bring to simmer, stirring often. Add cheese, mustard, and pepper sauce. Stir until cheese melts. Remove from heat. Season cheese sauce to taste with salt.

    Step 2

    Whisk eggs in medium bowl. Gradually whisk in 1 cup cheese sauce. Stir egg mixture into cheese sauce in saucepan.

    Step 3

    Meanwhile, cook pasta in large pot of boiling salted water until just tender but still firm to bite, stirring occasionally. Drain. Return to pot.

    Step 4

    Stir cheese sauce into pasta in pot. Transfer to prepared baking dish. do ahead Can be made 2 hours ahead. Let stand at room temperature.

    Step 5

    Preheat oven to 400°F. Bake pasta until cheese sauce is bubbling around edges and some ends of pasta are golden brown, 25 to 30 minutes.

    Step 6

    Let stand 15 minutes. Serve hot.

Test-kitchen:

Unlike classic mac and cheese, which is thickened by a roux (a flour and butter mixture), this one uses eggs to make a rich, gooey custard. But be careful when adding the hot cheese sauce to the eggs; you’ll need to whisk the sauce in slowly so that the eggs don’t curdle.

  • Nice! I don't know about the mustard but still comfort food! Doesn't get dry at all in the oven. Just perfect. A little parmesan on top is a plus!

  • Really nice recipe as is and will be good to use as a base to alter depending on our mood. I'm not sure why some of the comments but I guess a lot of folks want that over the top flavors but traditional mac and cheese done right isn't that powerful of flavor. If you want a strong flavor just add to taste before baking.

  • Loved it! Went smoky-bacon route though.. substituted 1 red onion for leeks and /- 1.5tsp chipotle chili powder for pepper sauce. Added 3 strips of bacon during onion prep (cooked til fat translucent). Removed bacon, chopped and added w/panko for topping prior to baking.

  • Edible but not worth the ingredients. The biggest mistake I made making this dish is trusting the recipe and baking it. Before I baked it, it was creamy and rich and good. After I baked it, it was dry, all the milk clumped into tiny little balls, and it didn't taste even remotely like it had a whole pound of cheese in it. Very disappointed! I should have just cooked it on the stovetop longer to cook the eggs through and not baked it. Will never make again.

  • 这是美味的,但是没有足够的精力。佛r all the dirty dishes that this created, I expected something better. I would suggest doubling the mustard. I managed to get 5 cups out of 3 large leeks. Texture was perfect.

  • I was also disappointed. Found the leeks to add a sweetness that I didn't enjoy. Not bad but not worth it.

  • Based on the glowing reviews, I was disappointed. We found it to be somewhat marginal at best. It could easily feed 8 to 10.

  • I made this last night using rigatoni instead of penne. Followed the recipe exactly. Delicious! Served along side grilled lamb chops. Everyone had seconds. The sauce was smooth, not curdled at all. I will definitely make this again. Some bacon would be a good addition.

  • This is a great grown-up mac'n'cheese. I've made it twice, and most recently served it as a side dish at Christmas Dinner and it was really well received, there wasn't a bit left at the end. Don't go light on the leeks, they are what makes this delicious. I had more luck with a yellowy cheddar as well.

  • I'm not generally a fan of creamy pasta dishes, but needed a baked dish to take to a gathering, and had everything available, so I made it. All I can say is YUM! I followed the recipe to the letter except I took the advice of some other reviewers and added some cubed pancetta in with the sauce, and topped with Panko. Superb! The flavor of the leeks is sweet and creamy and delicious. Obscene with a nice glass of red. Very rich, to be certain, but worth a try. Will definitely make again. And again.

  • Excellent recipe! I halved it, with 3 leeks, 1 shallot and 2 eggs. I used equal parts 6-year aged cheddar, Musser cheddar from Iowa, and Gruyere cheese. The mustard we had on hand was dijon with capers and tarragon - when I test-tasted this was way too sweet, so I added balsamic vinegar, which balanced it. For the hot sauce I used equal parts Valentina salsa picante (very flavorful) and Sriracha (very hot!). I baked it topped with a sprinkling of Panko bread crumbs, a bit of each cheese grated on top, plus a tiny bit of Italian truffle cheese to add an extra bit of flavor to the top crust. We paired it with a Pinot Noir from Bergstrom, Cumberland Reserve. This dish made a wonderful Sunday supper on a cold, snowy night in late March.

  • Made this tonight and followed the recipe except I topped it with a little panko and broiled it for a couple minutes at the end. One of the best baked pastas I've had. It was super easy to make and everyone loved it.

  • Great Mac-N-Cheese dish! We used lowfat milk and put panko breadcrumbs on top and it turned out great!

  • This recipe is so good I have made it a permanent fixture in my family cookbook. The leeks add a sweet flavor to this rich pasta and lightens it a bit, too. I seldom find a recipe that I find to be too perfect to change, but I prepare this one to the letter. I don't sweat the tempering of the eggs; I just wield a whisk with zest while adding the cheese mixture to the eggs, a little at a time.

  • This is good, but very rich, so I wouldn't make it too often but I would definitely make it again. I followed the recipe exactly but sprinkled parmesan cheese on top, and it was delicious!
