Ranch dressing has been the top-selling dressing in this country since 1992, when it overtook Italian. Given that the bottled stuff has 19 grams of fat and 180 calories per serving, something had to be done! We may want many things like our mamas’—but not the fat-laden version of this dressing.

Believe it or not, it wasn’t so long ago that most people thought blue cheese was a bit exotic—a stinky, strange cheese with (heaven forbid!) mold in its veins. But blue has gained traction because its rich, creamy texture and tangy taste are fabulous—whether eaten out of hand, crumbled over a salad, or stirred into a dressing. But this is no lean cheese, my friends. Thankfully, a little goes a long way, and there are great-tasting low-fat blue cheeses available in most major supermarkets today.

Real mayonnaise is made with egg yolks and oil—which might explain the 10 grams of fat per tablespoon. You can very easily wind up slathering at least a tablespoon or two on a sandwich. This very good approximation uses Greek yogurt as a base, rather than oil.

This is a healthy version of one of the greatest inventions of the 1980s: the hollowed-out deep-fried potato skins filled with sour cream, bacon, and cheese that first appeared on the menu at T.G.I. Friday’s in New York City. There are a few differences, though. Here, the potato skin is baked until crisp, not fried, and the fillings are all reduced-fat products. The result is a pretty spectacular loaded potato skin at one-third of the calories and less than one-fourth of the fat of the original.

Few dishes are as soul-satisfying and luxurious as a buttery-rich potato puree or mashed potatoes. I love mashed potatoes, but I know that they’re not particularly good for me. Cauliflower puree makes a truly superb substitute.

This was a tough one. Everyone loves cheesy garlic bread, but between the white bread, the butter, and the cheese, it’s a tough sell to the health-conscious. The task was to figure out how to get whole-wheat bread to respond like white bread. Toasting the bread first, then dipping it in chicken broth before topping it with a generous amount of low-fat cheese, and finally broiling it did the trick.

Though they are both outrageously rich pasta sauces, carbonara and Alfredo are distinctly different. The base for Alfredo is cream and Parmigiano-Reggiano. The base for carbonara includes onions, bacon or pancetta (originally it was guanciale—cured pigs’ cheeks), egg yolks, and Parmigiano-Reggiano or Pecorino Romano. At almost 1,000 calories per serving, this dish was ripe for a makeover.

Here’s a great steakhouse side dish that can do more harm than the red meat itself. Standard preparations make a bad boy out of an otherwise extraordinarily healthy vegetable. The problem with spinach is that it’s very lean and often bitter—which is why we sauté it in butter or douse it with cream. All-natural Greek yogurt has been employed here to help clean up its act.

The dirty little secret about Penne alla Vodka is not the vodka but the hefty amount of heavy cream. Vodka is colorless, odorless, and without much flavor—not really attributes of a superstar ingredient. It’s the combination of cream and tomato sauce that gives this dish its signature flavor. The traditional cream is swapped here for low-fat Greek yogurt.

Of all the dishes that were suggested for this book, mac ’n’ cheese came up most often. Everyone loves it—and everyone knows how nutritionally bad it can be. Calories start at 600 per serving and go into the thousands. It’s a dish that has become so rich that taming its fatty side proved to be quite a challenge. The base of the sauce in this version isn’t cream, but a puree of cooked onions and garlic. It gives the dish lots of flavor with not so much as a gram of fat. The very hot oven makes the breadcrumbs on top get nice and crunchy. It’s the combination of crisp and gooey textures that makes this a winning dish.

These little lasagnas, made with fat-free ricotta and reduced-fat mozzarella, are cheesy and satisfying and totally big on flavor. Make sure the dishes (8-inch, preferably) you use are broilerproof—they go under the flame to make the cheese brown and bubbling right before serving.

This is for the pasta shunners out there who still find themselves pining for a big, gooey serving of lasagna. Nothing can really replace the toothsome texture of fresh pasta, but given the amount of “bad” carbs a serving of pasta contains, it’s understandable that some choose to avoid it altogether. Thin slices of zucchini and eggplant stand in for the pasta in this lasagna, made with fat-free ricotta and low-fat marinara sauce. It all adds up to a truly delish alternative to traditional high-calorie lasagna.

Gnocchi are small dumplings made with cooked potatoes and just enough flour to hold them together. I swapped the traditional white potatoes for far-more-healthful sweet potatoes and paired the gnocchi with broccoli. The color combo is fabulous and so is the flavor, thanks to a sprinkling of Parmigiano-Reggiano. And while many gnocchi recipes include a cream- or butter-based sauce for tossing, these are served in a garlicky broth stirred together with a bit of Greek yogurt instead. They take a little while to make, but given the great taste and the powerhouse nutritional value of sweet potatoes—and just under 350 calories per serving—they’re more than worth the trouble.

I once ate true Fettuccine Alfredo at Ristorante D’Alfredo in Rome, where a giant picture of its namesake owner hangs on the wall. The big flavors of the dish were brought to bear by combining outsized amounts of butter and Parmigiano-Reggiano. It was that simple: butter and cheese. Not so simple, though, if you’re watching your waistline. This version eliminates the cream that many American versions call for but retains a little bit of the butter for flavor. The velvety-smooth texture is re-created with yogurt and thickened chicken broth. It may not be as authentic as the original, invented by Alfredo di Lelio, but it’s a very tasty version we can all live with (for a very long time).

This recipe calls for lean boneless pork loin, and to avoid added sugar, we use fresh apples instead of applesauce. Tart Granny Smiths contribute great texture and flavor—as does a grainy Dijon mustard.

Who would have thought those thin little crepes filled with ricotta and baked in red sauce and cheese could be so diabolically caloric? The fat in the ricotta, the fat in the mozzarella, the fat in the Parmigiano-Reggiano, and even the fat in the olive oil—it adds up quickly. A typical serving has about 46 grams of fat and more than 900 calories. With a few clever swaps, I got it down to just over 8 grams and 200 calories. A few meals like this, and you’ll be into your little black dress in no time.

Swapping the traditional crown of mashed white potatoes for a topping of seasoned cauliflower puree made with Greek yogurt saves a load of calories and carbs—enough to enjoy this English pub dish with a nice pint, if you like.

Purists insist that skirt steak is the only cut of beef from which to make fajitas. Skirt steak is delicious—mostly because of the fat marbling through it. That’s why this recipe calls for lean filet mignon: it has significantly less fat than skirt steak. The condiments more than make up for the flavor that fat provides.

Béarnaise is one of the classic French sauces. Its standard formulation includes a lot of butter and egg yolks. In this version, I kept the licorice-tasting tarragon that’s a hallmark of the sauce and let the fat and calories go.

Few dishes are as tasty and flavorful as a good curry. Unfortunately, the amount of ghee (clarified butter) and full-fat yogurt used in a typical curry makes for a lot of XXL T-shirts. Here, lean, tender beef, intense seasoning, lots of fresh vegetables, and 5%-fat yogurt make for a skinny jeans day instead.
