Beautiful Food

I’m pretty excited about this post. It features some of my favorite ingredients: butternut squash, caramelized onions, and sage. And it’s perfect for fall! But best of all, it’s a collaboration with an amazing food photographer, Rikki Snyder. Oh, and it has a concept too! A concept!

Butternut Squash & Caramelized Onion Flatbread
After emailing back and forth for a while, Rikki and I decided to work together on a few posts. I’ve always felt that my strength as a food blogger is recipe development; while I love taking pictures, I’d be lying if I said it wasn’t a struggle at times. And since Rikki takes gorgeous photos, it seemed like a fun idea for me to develop some recipes and for Rikki to photograph them. Today I’m posting the first recipe, a Butternut Squash and Caramelized Onion Flatbread, and tomorrow Rikki will be publishing a recipe for Penne with Butternut Squash and Kale on her blog.

Fontina Cheese & Sage
The common denominator in the recipes? Butternut squash! (And caramelized onions too.) Fall is typically a busy time. The lazy, relaxed days of summer are over. Now the kids are back in school, days are shorter, and easy meals are much-needed. Well, here are two meal ideas to make life a little bit less hectic—at least around dinnertime.

Butternut Squash & Caramelized Onion FlatbreadAbout the Recipe

Both the pasta and the flatbread start with roasted butternut squash and caramelized onions. You can make these over the weekend or the night before. You’ll use half of them in each recipe. While the roasted squash and caramelized onions take a little bit of time to make, they’re fairly hands-off recipes. With both of those prepared in advance, the pasta and flatbread are each done in 20 minutes or less.

The best thing about these two meals is that not only are they easy, but they’re delicious. Because even though fall is a busy time, rushed meals don’t always have to come out of a box or a can—with a little bit of planning, you can have a quick homemade meal like this rustic butternut squash flatbread. And trust me, having eaten many meals from a box in my day, this flatbread is way better.
