Current mood: eating these toasts 24/7.

It’s safe to say that if you love caramelized onions, you are destined to adore this toast. I happen to love onions pretty much any way I can have them — pickled, fried, caramelized? yes yes yes — so for me, this toast is perfect.

You start by caramelizing the onions, which is a bit of an artform unto itself. The trick with caramelizing is patience, and as a New Yorker, I have none. But when it comes to onions, I somehow manage to take it slow and let the onions do their thang. That “thang” being sautéd in olive oil over a medium-high flame for about 30 minutes.

30 minutes doesn’t sound too bad, I know. But here’s the thing — you need to stir them routinely. Like, every five minutes. So while this is admittedly a bit annoying, it’s also completely worth it. You want your onions to evenly cook up golden and tender, not crisp and burnt. Constant attention is the only way to achieve this, so throw on a podcast and listen while you stir.

When the onions are nearly finished, lightly toast slices of sourdough bread in the oven (like 2 mins) then pile high with baby spinach, onions, and an offensive serving of cheddar cheese. Pop back in the oven until hot and melty, season with everything bagel seasoning, then eat!

It takes a bit of time, but these honestly couldn’t be simpler.

The combination of crisp bread, buttery onions, and sharp cheddar cheese is SO good. It’s like an American variation of french onion-soup… on toast. Add to that some spinach for some health + greens (yum) and this couldn’t be more delightful.

Except… it COULD. Because that everything bagel seasoning on top is straight genius! It adds a nutty, garlicky, slightly salty finish that brings this straight into savory heaven. I truly couldn’t love this little toast more, and I’m confident you will too. Xo

Caramelized Onion, Spinach, & Cheddar Toasts w/ Everything Bagel Seasoning


  • 1 1/2 tbsps extra virgin olive oil
  • 2 large yellow onions, sliced thin
  • 7 slices sourdough toast
  • 2 – 3 oz baby spinach lettuce
  • 3 cups shredded cheddar cheese
  • Trader Joe’s “Everything Bagel” seasoning


  1. In a large skillet warm the olive oil over a medium-high flame, swirling to coat. Add the onions, sautéing until caramelized, about 30 minutes. Stir routinely throughout cooking.
  2. Pre-heat oven to 400F.
  3. When the onions are almost finished cooking, place the slices of sourdough bread on an ungreased baking sheet and toast on oven middle rack for about 3 minutes until crisp but not brown. Remove and keep oven heated.
  4. Layer the sourdough slices with spinach lettuce, caramelized onion, and cheddar cheese. Return to oven middle rack and toast for another 3 – 5 minutes until the cheese is melted and bubbly. Sprinkle each slice with “everything bagel” seasoning, then immediately eat.
