After lots of up-and-downs with weeknight dinners, I landed on this super filling casserole—it's got ground beef, tender zucchini, and fluffy quinoa all mixed together. It’s the easy dinner I fall back on when I want food that feels cozy, but won’t slow me down. Think of it as a healthy, cozy spin on lasagna—same comfy vibes, just lighter and packed with goodness.

When I took this to a get-together last month, people kept refilling their plates and hunted me down for how to make it. Even my neighbor’s kids (who usually pick at everything) finished every bite. Can’t get a better sign it’s good than that.

Real Kitchen Vibes

When this bakes, the whole place starts to smell like a tiny Italian bistro. I always grab it fresh from the oven—the cheese pulls are next level, and the edges are crispy perfection. Usually, I toss together a salad while it cooks, but honestly, this one stands fine on its own.

Make It Yours

I swap things up with whatever’s hanging out in my fridge. Last time I had extra yellow squash, so I chopped it in with the zucchini—so tasty. If my vegetarian sister pops in, I just use lentils and mushrooms instead of meat and nobody complains. When summer hands me too many tomatoes, I just toss in fresh ones after cooking them down a bit.

Staying Fresh

Here’s the wild part—this is actually tastier after a night in the fridge. All the flavors meld together and turn up the yum. I cut leftovers and stack them up for grab-and-go lunches. Quick tip: slice it up before tossing in the freezer, so you’re not trying to chisel out pieces like I did once—never again!

Go-To Tricks

I’ve learned a few hacks with this dish. If your zucchini is super juicy, just lay it out on paper towels till you’re set to cook. Don’t hold back on the cheese at the end. That’s the part everybody goes nuts for. My grandma always said casseroles should be generous—totally agree.

Steps

Step 01

Set your oven to 375°F and give a 9x13 baking dish a quick grease. Get quinoa ready if you don’t have it cooked yet.

Step 02

Warm up 1 tablespoon of olive oil on medium heat. Toss in ground beef, diced onion, and ½ teaspoon salt. Stir and cook for 5 minutes. Move it all into the baking dish.

Step 03

Using the same pan, heat the rest of the olive oil. Add chopped zucchini and the rest of the salt. Cover and cook for 5 minutes until soft. Stir in tomato sauce and the drained tomatoes.

Step 04

Mix the cooked quinoa, seasoned zucchini blend, all herbs, and 1 cup of mozzarella straight into the dish with the meat. Stir it well and spread evenly.

Step 05

Sprinkle the top with the remaining mozzarella. Bake it for 25 minutes, then give the cheese a golden finish in the broiler for 2-5 minutes. Let it sit for 5 minutes before digging in.
