Baked Marry Me Chicken Casserole

If you ask me, this is the kind of casserole that lives up to its name.

This one-pan dinner brings together tender chicken breasts and fluffy rice with a rich, creamy sauce that’s loaded with sun-dried tomatoes and garlic. The sauce gets its depth from white wine, Parmesan cheese, and a splash of balsamic vinegar.

Everything bakes together in the oven, so the flavors have time to blend while the chicken stays juicy. A sprinkle of fresh thyme and red pepper flakes adds just enough warmth without overwhelming the dish.

It’s the kind of meal that feels special enough for company but easy enough for a weeknight dinner.

What Kind of Chicken Should I Use?

For this casserole, boneless, skinless chicken breasts are your best bet since they cook evenly and are easy to slice or shred. If you can only find really thick chicken breasts at the store, consider pounding them to an even thickness or slicing them in half horizontally so they cook through at the same rate as the rice. Chicken thighs would also work great here if that’s what you prefer – they’re a bit more forgiving and won’t dry out as easily, plus they add extra flavor to the dish. Just make sure whatever you choose is around the same size so everything finishes cooking at the same time.

Options for Substitutions

This casserole is pretty forgiving when it comes to swaps, so here are some options if you need to make changes:

• Chicken breasts: Chicken thighs work great here and actually stay more moist during baking. You can also use pre-cooked rotisserie chicken – just shred it and add it in the last 15 minutes of cooking.
• Sun-dried tomatoes: If you don’t have sun-dried tomatoes, you can use chopped fresh tomatoes or even canned diced tomatoes. Just drain them well and add a pinch of extra salt since sun-dried tomatoes are more concentrated in flavor.
• White wine: No wine on hand? Replace it with the same amount of chicken broth plus 1 tablespoon of lemon juice to keep that tangy brightness.
• Heavy cream: You can use half-and-half for a lighter version, or even whole milk mixed with 2 tablespoons of cream cheese to maintain that creamy texture.
• Shallot: A small yellow onion or 3-4 green onions work just fine if you don’t have a shallot.
• Rice mix: Plain white or brown rice works too – just cook it according to package directions and season with a bit of extra salt and herbs.

Watch Out for These Mistakes While Cooking

The biggest mistake when making this casserole is overcooking the chicken during the initial sear, which leads to dry, tough meat after baking – remember, you’re only browning it at this stage, not cooking it through.

Since you’re deglazing the pan with white wine, make sure to let it simmer long enough to cook off the alcohol (about 3 minutes), otherwise you’ll end up with a harsh, boozy flavor that overpowers the dish.

Don’t skip seasoning the chicken with salt and pepper before searing, as this is your main opportunity to season the meat itself, and be careful not to let the garlic burn when sautéing – burnt garlic turns bitter and can ruin the whole sauce.

For the creamiest results, stir the cream in gently and avoid boiling it, and if your sauce seems too thick, add a splash more broth before baking to keep everything moist.

What to Serve With Marry Me Chicken Casserole?

Since this casserole already has rice built right in, I like to keep the sides simple and let the creamy, sun-dried tomato flavors shine. A crisp green salad with a light lemon vinaigrette is perfect for cutting through all that richness, or you could go with some roasted green beans or asparagus tossed with a little olive oil and garlic. Garlic bread or crusty French bread is always a good call for soaking up the extra sauce, and if you want something green and easy, steamed broccoli or a Caesar salad both work great. This dish is pretty filling on its own, so you really don’t need much more than a simple veggie and some bread to round out the meal.

Storage Instructions

Store: This casserole keeps really well in the fridge for up to 4 days in an airtight container. The flavors actually get even better the next day as everything has time to meld together, making it perfect for meal prep or leftovers throughout the week.

Freeze: You can freeze this casserole for up to 3 months, either in individual portions or as a whole. Just make sure it’s completely cooled before freezing, and I recommend using a freezer-safe container with a tight lid to prevent freezer burn.

Reheat: Warm it up in the oven at 350°F covered with foil until heated through, about 20-25 minutes from the fridge or 35-40 minutes from frozen. You can also microwave individual portions for 2-3 minutes, stirring halfway through to make sure it heats evenly.

• Carbohydrates: 200-230 g

Ingredients

For the rice:

• 2.25 cups chicken broth
• 0.75 tsp salt
• 2 pkg rice mix

For the chicken:

• 2 tbsp olive oil
• 2.5 tbsp butter
• 4 chicken breasts
• 1/4 tsp black pepper
• 0.75 tsp salt

For the sauce:

• 2.5 tbsp butter
• 3/4 cup sun-dried tomatoes
• 1 shallot, finely minced
• 6 garlic cloves, minced
• 1 tsp dried oregano
• 1/2 tsp red pepper flakes
• 2 tbsp tomato paste
• 1/2 cup dry white wine
• 1/2 cup chicken broth
• 1/2 cup heavy cream
• 1 tbsp balsamic vinegar
• 1.75 oz Parmesan cheese, grated
• 1/2 tsp fresh thyme leaves

Step 1: Prepare the Rice Base

• 2.25 cups chicken broth
• 0.75 tsp salt
• 2 pkg rice mix

Preheat your oven to 350°F.

In a pot, bring 2.25 cups chicken broth and 0.75 teaspoon salt to a boil over medium-high heat.

Stir in the rice mix, return to a boil, then reduce heat to low and cover.

Simmer for 15 minutes until the rice is tender and liquid is absorbed.

This gives you a head start on cooking while you prepare the chicken and sauce.

Step 2: Sear the Chicken

• 4 chicken breasts
• 0.75 tsp salt
• 0.25 tsp black pepper
• 2 tbsp olive oil
• 2.5 tbsp butter

While the rice cooks, season the chicken breasts evenly on both sides with 0.75 teaspoon salt and 0.25 teaspoon black pepper.

Heat 2 tablespoons olive oil and 2.5 tablespoons butter in a large skillet over medium-high heat until shimmering.

Sear the chicken for 6 minutes per side until golden brown on the outside (it won’t be fully cooked through).

Transfer the seared chicken to a cutting board and set aside.

I like to keep the pan on the heat because you’ll use those flavorful browned bits for your sauce.

Step 3: Build the Sun-Dried Tomato Sauce

• 2.5 tbsp butter
• 1 shallot, finely minced
• 6 garlic cloves, minced
• 0.75 cup sun-dried tomatoes
• 1 tsp dried oregano
• 0.5 tsp red pepper flakes
• 2 tbsp tomato paste
• 0.5 cup dry white wine
• 0.5 cup chicken broth

In the same skillet with the chicken drippings, melt 2.5 tablespoons butter over medium heat.

Add the minced shallot and garlic, cooking for 1 minute until fragrant.

Stir in the sun-dried tomatoes, dried oregano, and red pepper flakes, cooking for 2 additional minutes to release the flavors.

Add the tomato paste and cook for 1 minute, then deglaze the pan with the dry white wine and 0.5 cup chicken broth, scraping up any browned bits from the bottom.

Simmer for 3 minutes to reduce slightly and mellow the acidity.

This layering of aromatics and tomato paste creates the depth that makes this dish so special.

Step 4: Create the Creamy Sauce and Combine

• 0.5 cup heavy cream
• 1 tbsp balsamic vinegar
• 1.75 oz Parmesan cheese, grated
• cooked rice from Step 1

Remove the sauce from heat and stir in the heavy cream, balsamic vinegar, and 1.75 ounces grated Parmesan cheese until smooth and well combined.

Season to taste with a pinch of salt and pepper if needed.

Add the cooked rice from Step 1 to the sauce and fold gently to combine everything without breaking up the rice grains too much.

This cream-based sauce is what gives the dish its rich, luxurious character.

Step 5: Assemble and Bake

• rice and sauce mixture from Step 4
• seared chicken from Step 2

Spread the rice and sauce mixture into a 9×13 inch baking dish.

Nestle the seared chicken breasts from Step 2 into the rice mixture, pressing them down slightly so they’re partially submerged.

Bake uncovered at 350°F for 30 minutes until the chicken is cooked through (internal temperature of 165°F) and the casserole is heated through.

Step 6: Finish and Serve

• 0.5 tsp fresh thyme leaves

Remove the casserole from the oven and sprinkle the remaining Parmesan cheese and fresh thyme leaves over the top as garnish.

Let it rest for 5 minutes before serving to allow the flavors to settle and the chicken to retain its juices.
