Summer squash gratin with nutmeg béchamel


Summer squash gratin

When the doorbell rings and you find a 2-foot tall little girl standing there holding an armful of fresh zucchini, you can’t help but smile. She’s shyly grinning while barely hanging on to the three large squash that are about the size of her arms. She hardly says a word, but you can tell how proud she is that these came out of her garden. Her dad grew these – mighty impressive in the eyes of a toddler. Turns out our neighbor’s garden was overflowing with summer squash that nearly doubled in size overnight. I can relate to her awe – it’s the same marvel I felt when I saw the gargantuan zucchini popping up out of the compost pile as a child. And watermelon. Those things can grow anywhere, I tell ya.

Summer Squash Gratin with Béchamel

We go bananas over squash in the wintertime – butternut squash soup, spaghetti squash bolognese, pumpkin everything – but there’s a special place in my heart for summer squash. Could this be because zucchini was a major food group in my family from June through August? Probably. It’s gotta be cooked just right though – none of that mushy baby food-like stuff. Lightly softened with a bite, and properly seasoned. Ever since I discovered the speed with which my new food processor can thinly slice squash, it’s been all squash all the time in my kitchen. No one’s complaining.

Summer Squash Gratin with Nutmeg Béchamel

Most of my culinary experiments these days involve finding ways to take the gluten out of my cravings. You know that moment when you’re planning a dinner party and your house guests tell you that they’ll eat anything except _(blank)_ and for some reason snails or whatever they detest is a major component of every single recipe that sounds good? And you can’t possible fathom cooking anything else. Even if you’ve never even actually eaten snails.

Same premise with me and gluten. You tell me I can’t eat it and it’s the only thing I want to eat and OMG-why-don’t-we-have-anything-to-eat-in-this-house? Pizza, pasta, bread, and creamy béchamel sauce. All filled with flour. So when your new favorite food (it’s always the biggest deal because it’s your favorite food this week) is going to cause you a massive migraine, you substitute. In this case, the flour thickening agent in this beloved nutmeg béchamel gets swapped out for masa harina. Pitch hitter. You wind up with the rich velvety vegetable lasagna you long for, without the headache-inducing ingredients.

Yields: One 9x12 casserole, about 8-10 side servings
  • 3 cloves garlic, minced
