spinach cheese bars

I know — spinach in a cheesy baked bar sounds like a hard pass. But these are rich, custardy, and packed with melty Monterey jack, and you genuinely cannot taste the spinach. They come together in one bowl, no crust, no fuss, and they disappear off the tray faster than anything else I bring.

Why You’ll Love It

You can’t taste the spinach — the cheese and eggs completely take over, so even spinach skeptics go back for seconds
One bowl, no crust — dump, stir, bake, no rolling or fussing required
Rich and custardy — more like a savory cheese bar than a vegetable dish
Goes fast — these disappear off a tray quicker than almost anything else I make
Just as good cold — straight from the fridge, no reheating needed

A Few Thoughts on the Ingredients

The cheese is really the whole show here, so don’t skimp — get an actual block of Monterey jack, not the pre-shredded bag stuff, which never melts the same way and honestly tastes a little waxy to me. I’ve used pepper jack a couple times when I wanted a little kick and nobody complained, though my husband did sweat through dinner that one time, which I found more amusing than I probably should have.

As for the spinach — squeeze it dry. I cannot stress this enough. Squeeze it until your hands hurt, squeeze it more than you think is necessary, because if you don’t, you end up with a watery, sad situation in the middle of your pan and it just never sets right. I usually do this in batches in a clean dish towel, twisting it like I’m wringing out a swimsuit, and even then I sometimes feel like there’s more water hiding in there somewhere.

What You’ll Need

1 package (12 oz) frozen chopped spinach, thawed and squeezed dry — really dry, see above
1 cup milk, whatever you’ve got in the fridge, I’ve used 2% and whole and never noticed a difference
1 cup all-purpose flour
1 teaspoon baking powder
1 teaspoon salt
1 stick Butter, softened — not melted, just soft enough to give when you poke it
1 pound Monterey jack cheese, cubed (small-ish cubes, though I’m not out here measuring with a ruler)
2 large eggs

How I Actually Make These

Preheat your oven to 350. While that’s heating, beat together your softened butter and the eggs — I do this right in the same bowl I’m going to mix everything else in, because dishes are the enemy and I refuse to create more of them than necessary. It’ll look a little broken-up and weird at first, kind of curdled almost, don’t panic, that’s normal.

Mix in the milk, flour, baking powder, and salt. I usually just dump these in one at a time and stir with a wooden spoon, nothing fancy, no mixer required. The batter at this stage is thin, almost like pancake batter, and every single time I make this I have a brief moment of doubt where I think, this is never going to turn into squares, this is going to be soup. It’s not soup. Trust the process, or trust me, anyway.

Fold in your spinach and the cubed cheese. This is the part where it starts looking like something — all those little flecks of green against the white cheese cubes, and the batter gets heavier, more substantial.

Spread it into a greased 9×13 pan — I use the cooking spray, the cheap kind, doesn’t matter — and get it as even as you can, though it doesn’t have to be perfect because it’ll settle some as it bakes.

Bake for 40 to 45 Minutes. I will say my oven runs a little hot, so I usually start checking around the 38-minute mark, looking for the top to be golden and maybe just slightly puffed, with the edges pulling away from the pan a touch. Let it sit for a bit before you cut it — I know, I know, the waiting is the worst part — because if you cut it too soon it just falls apart into a mess instead of nice clean squares. Once it’s cooled some, cut it into small squares. They’re rich, so you don’t need big pieces.

And here’s the part people don’t believe: you can eat these cold, straight out of the fridge, and they’re honestly almost better that way. My youngest used to eat these cold for breakfast before school, standing at the open fridge door in his socks, which drove me up a wall for reasons that had nothing to do with the spinach squares and everything to do with him letting all the cold air out.

If You Want to Switch It Up

My daughter makes hers with a sharp cheddar mixed in with the jack, about half and half, and swears it’s better, though I’m not entirely convinced — I think she just likes an excuse to use up the cheddar that’s always going stale in her fridge. I tried adding a handful of chopped green onions once and it was fine, not bad, but it didn’t really add much, so I haven’t bothered since. You could probably do fresh spinach instead of frozen if you wanted to cook it down yourself first, but that’s extra work for, in my opinion, the same result, and I am all about the path of least resistance these days.

Keeping Them Around

These keep in the fridge for about five days, covered, and they reheat fine in the microwave for maybe twenty seconds if you want them warm, though like I said, cold is genuinely a valid way to eat these. I’ve frozen the leftovers before too, wrapped tight, and they thaw out okay, maybe just a touch softer than fresh. I did once leave a container of these on the counter overnight by accident — long story, don’t ask — and had to toss the whole batch, which still bothers me a little when I think about it.
