Chimichurri Chicken Casserole
A bright twist on classic chicken casserole — this one gets its punch from Argentine chimichurri, a hit of lime, and just enough heat to keep things interesting.

This isn’t your usual baked casserole. Think tender chunks of chicken simmered in a chimichurri marinade — full of parsley, garlic, and that unmistakable tang that makes everything taste alive.
I started making this version after realizing how often chimichurri ended up on my table despite living far from Argentina: Drizzled over steak, spooned on roasted vegetables, or tossed with potatoes. One day, I thought, ‘Why not make it the base for a one-pan chicken dish?’
It’s quick to prepare, deeply flavorful, and flexible — you can marinate the chicken earlier in the day and cook it just before dinner. It’s fresh, herby, and perfectly balanced by the slight smokiness of the salt and the brightness of lime. Serve it with fries, roasted potatoes, or a side of rice to soak up all that gorgeous sauce.
How I Make It
I start by marinating the chicken: In a bowl, combine 1 cup of chimichurri with the chicken chunks. Toss well to coat, cover, and let it rest in the fridge for at least 30 minutes (2–3 hours is even better).
Then, I prep the base of the dish. Heat 5–6 tablespoons of extra virgin olive oil in a large pan or cast-iron skillet. Add the diced onion, minced garlic, and the white part of the green onions. Sauté until the veggies are fragrant and lightly golden.
Add the marinated chicken pieces (keep the leftover marinade for later). Let them brown on all sides — don’t rush this step; it builds flavor. Then, I pour in the remaining marinade and a handful of fresh parsley. I season with salt and pepper. I use smoked salt, which works great with chicken!
Now it’s time to let the chicken simmer. Add ½ glass of water, broth, or white wine to deglaze the pan, scraping up the browned bits.
Lower the heat and let everything simmer gently for about 20 minutes, until the chicken is tender and the sauce slightly thickened. If you don’t find that it has thickened enough, adding a tablespoon of cornstarch (dissolved in a little water) can make all the difference.
Finally, I turn off the heat, stir in the green parts of the onions, squeeze in a bit of lime juice, and serve immediately with fries.
