Marty Rosencranz of River Vale, New Jersey, writes: "Even though I am a professional chef — at the Valley Brook Golf Club in New Jersey — when I cook at home I make dishes that are good but fast. The warm steak sandwich is one of the best things to eat for lunch on a cold day."

Croissant steak sandwiches with caramelized onions and horseradish mayonnaise Although this sandwich tastes great with a croissant, any bread can be used.

Recipe notes

Our Favorite French Onion Soup

Caramelized onions, melty Gruyère, and a deeply savory broth deliver the kind of comfort that doesn’t need improving.

Butternut Squash–Kale Salad With Roasted Garlic Vinaigrette

Round out these autumn greens with tart pomegranate seeds, crunchy pepitas, and a shower of Parmesan.

Mascarpone Cheesecake

An extra-silky filling (no water bath needed!) and a smooth sour cream topping make this the ultimate cheesecake.

White Bean Turkey Chili

A dash of cocoa powder adds depth and richness to the broth of this easy turkey chili.

Béchamel Sauce

This classic 15-minute sauce is your secret weapon for homemade mac and cheese, chowder, lasagna, and more.

Dulce de Leche

Make this versatile caramel at home with our slow-simmered method using milk and sugar—or take one of two sweetened condensed milk shortcuts.

Smothered Italian Sausage

This is what I call a fridge-eater recipe. The key here is getting a nice sear on the sausage and cooking the tomato down until it coats the sausage and vegetables well.

Classic Potato Latkes

Crispy. Golden. Fluffy. Bubbe would approve.
