1. Chicken Spaghetti Casserole

This Southern-style chicken casserole is melty, saucy, and easy to double for a party. It blends tender shredded chicken with sauced spaghetti and a blanket of cheddar for that gooey, comforting pull. It’s a crowd-pleasing weeknight winner when you want comfort without fuss.

• I like using a 9×13 baking dish so there’s room for nice edges and even baking.

Ingredients

• 12 oz spaghetti
• 4 cups shredded rotisserie chicken
• 2 tbsp butter
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 1 can (10.5 oz) cream of chicken soup
• 1 cup sour cream
• 1 cup milk
• 1 tsp smoked paprika
• 2 cups shredded sharp cheddar, divided
• 1/2 cup grated Parmesan
• Salt and pepper, to taste
• 2 tbsp chopped fresh parsley (optional)

Instructions

1. Preheat oven to 350°F (175°C). Lightly grease a 9×13 baking dish.
2. Cook spaghetti according to package until al dente. Drain and set aside.
3. In a large skillet, melt butter over medium heat. Add onion and cook 4–5 minutes until soft. Add garlic and cook 30 seconds.
4. Stir in cream of chicken soup, sour cream, milk, smoked paprika, salt and pepper. Heat until just warmed and combined.
5. Add shredded chicken and cooked spaghetti to the skillet. Toss gently to coat.
6. Stir in 1 cup cheddar and half the Parmesan. Taste and adjust seasoning.
7. Transfer mixture to the prepared baking dish and smooth top. Sprinkle remaining cheddar and Parmesan evenly.
8. Bake 20–25 minutes until cheese is melted and edges are bubbling and golden. If you want a crispier top, broil 1–2 minutes watching carefully.
9. Let rest 5–10 minutes before slicing. Check that internal temp reaches 165°F with a digital kitchen thermometer if you want precision.

How to Serve It

Serve slices on warmed plates and garnish with chopped parsley. Pair with a crisp green salad and iced tea. Store leftovers in airtight food containers in the fridge for 3–4 days; reheat covered at 350°F until warmed through. This casserole scales well—double for a crowd, or halve for two.

2. Layered Enchilada Casserole

All the bold flavors of enchiladas without the rolling: layers of soft corn tortillas, seasoned chicken, beans, enchilada sauce, and melty Monterey Jack. This easy casserole keeps assembly simple and bakes in under an hour, so it’s great for a crowd or potluck.

• For cleanup and even browning, I use a rimmed heavy duty baking sheet under the pan to catch any drips.

Ingredients

• 12 corn tortillas, torn into pieces
• 3 cups shredded rotisserie chicken
• 1 can (15 oz) black beans, drained and rinsed
• 1 can (10 oz) red enchilada sauce
• 1 cup frozen corn, thawed
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 tbsp taco seasoning
• 2 cups shredded Monterey Jack (or cheddar blend)
• 1/2 cup chopped cilantro
• 1 cup salsa for serving
• Lime wedges, for serving
• Salt and pepper, to taste

Instructions

1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 pan.
2. In a skillet, sauté onion 3–4 minutes until translucent. Add garlic and taco seasoning; cook 30 seconds.
3. Stir in shredded chicken, black beans, and corn. Add 1/2 cup enchilada sauce and heat through. Season with salt and pepper.
4. Spread a thin layer of enchilada sauce across the bottom of the pan (wet-to-dry layering helps prevent sogginess).
5. Layer torn tortillas to cover the bottom, followed by half the chicken mixture and 1 cup cheese. Repeat layers, finishing with tortillas, sauce, and remaining cheese.
6. Cover with foil and bake 20 minutes. Uncover and bake another 10 minutes until cheese is bubbly and edges brown.
7. Let rest 5 minutes before cutting. Top with chopped cilantro and lime wedges.

How to Serve It

Spoon onto plates and add salsa, avocado slices, and extra hot sauce if you like spice. Serve with a side of cilantro-lime rice and refried beans. Store in glass meal prep containers for up to 4 days. This is a great make-ahead dish; assemble in a foil pan and bake the next day.

3. In the same skillet, add onion and sauté until soft, about 5 minutes. Add spinach and cook until just wilted.
4. In a bowl, whisk together sour cream, milk, Dijon, smoked paprika, salt and pepper.
5. Parboil pierogis 3 minutes (follow package quick-boil guidance) then drain.
6. Toss pierogis with sausage, onion-spinach mix, and sauce. Stir in 1 cup cheddar.
7. Transfer to baking dish, top with remaining cheddar, and bake 15–20 minutes until bubbly and lightly browned.
8. Let sit 5 minutes; garnish with chives.
