So if you’re looking for something warm, satisfying, and absurdly easy to throw together, this Creamy Ranch Chicken Spaghetti Casserole might just become your new go-to dinner. It’s simple enough for a weeknight but also feels like you put in actual effort (even if you didn’t).
Also… bacon. Yes, there’s bacon. You’re welcome.
What You’ll Need
Here’s the quick breakdown of what’s going into this creamy casserole situation:
| Ingredient | Amount | Notes |
|---|---|---|
| Spaghetti | 16 oz | Cooked al dente |
| Bacon | 8 strips | Cooked and crumbled |
| Cooked chicken | 3 cups | Shredded or chopped |
| Cream cheese | 8 oz | Softened |
| Sour cream | 1 cup | Adds that creamy tang |
| Cream of chicken soup | 1 can (10.5 oz) | Classic casserole base |
| Milk | 1 cup | Helps loosen the sauce |
| Ranch dressing seasoning mix | 1 packet (1 oz) | Store-bought or homemade |
| Cheddar cheese | 8 oz | Shredded, half for inside, half for topping |
| Fresh parsley (optional) | To taste | For garnish |
If you want to prep ahead, go ahead and cook the bacon and chicken the day before. Makes assembly that much faster.
Tools You’ll Need
Simple tools. Nothing fancy.
- Large pot (for pasta)
- Skillet (for bacon)
- Mixing bowls
- Whisk
- 9×13 casserole dish
- Wooden spoon or spatula
- Cheese grater (if you’re shredding your own, which you should)
Pro Tips
Before you get going, a few things that’ll make this smoother than that first bite of gooey, melty casserole:
- Cook the pasta just under al dente
You’re going to bake this, and spaghetti keeps soaking up liquid. If it’s already fully cooked, it’ll go mushy faster than you can say “where did my texture go?” - Shred your own cheese
Pre-shredded cheese has anti-caking agents. And while I love convenience, it just doesn’t melt the same. Take the extra minute to grate it. Worth it. - Let it rest after baking
Don’t dive straight in like a hungry raccoon. Let it sit for 5–10 minutes so the sauce can set up a bit. Makes serving way less messy. - Use rotisserie chicken if you’re short on time
Seriously a lifesaver. Shred it up and move on with your life. - Add veggies if you must
This casserole is flexible. Toss in steamed broccoli, peas, or even spinach if you’re trying to sneak in some green.
Substitutions and Variations
Because not everyone keeps the same pantry:
| Original | Substitution | Why It Works |
|---|---|---|
| Spaghetti | Penne, rotini, gluten-free pasta | Holds sauce well |
| Cream of chicken soup | Cream of mushroom, cream of celery | Slightly different flavor, same texture |
| Sour cream | Greek yogurt | Similar tang, higher protein |
| Cheddar cheese | Mozzarella, Monterey Jack, Colby Jack | Just switch up the flavor vibes |
| Chicken | Turkey, tofu, or leftover roast | Works well with the same seasoning |
Feel like spicing it up? Add a pinch of cayenne or some crushed red pepper flakes to the sauce. Ranch and heat? Yes please.
Make Ahead Tips
You can totally make this ahead. In fact, it might taste even better when the flavors have had time to hang out.
- Assemble now, bake later: Put the whole thing together, cover, and refrigerate for up to 24 hours. Let it sit out at room temp for 20–30 minutes before baking.
- Freezer friendly: Assemble, cover tightly with foil, and freeze for up to 2–3 months. Defrost in the fridge overnight, then bake as usual.
How to Make Creamy Ranch Chicken Spaghetti Casserole
Here’s the full walk-through. No fluff. Just steps.
- Preheat your oven to 350°F.
- Cook the spaghetti
Bring a big pot of salted water to a boil. Cook the spaghetti just to al dente. Drain and set aside. - Cook the bacon
Fry the bacon in a skillet over medium heat until crispy. Drain on paper towels, then crumble. Try not to eat half of it while doing this. - Mix the sauce
In a large mixing bowl, whisk together the cream cheese, sour cream, milk, ranch mix, and cream of chicken soup until smooth and creamy. - Combine it all
Add the cooked spaghetti, shredded chicken, crumbled bacon (save a little for topping), and HALF of the cheddar cheese. Stir everything together gently until coated. - Assemble the casserole
Pour the mixture into a greased 9×13 baking dish. Sprinkle the remaining cheese and reserved bacon over the top. - Bake
Pop it into the oven for 25–30 minutes, or until bubbly and golden on the edges. - Cool slightly
Let it sit for 5–10 minutes before serving so the sauce doesn’t run all over the place.

For special diets:
- Low-carb: Swap spaghetti with spiralized zucchini or shirataki noodles.
- Gluten-free: Use GF pasta and double-check your ranch packet and soup.
- Dairy-free: This one’s tough. You’d need dairy-free cream cheese, cheese, and sour cream. But yes, it’s possible.
Meal pairing ideas:
- A super simple green salad with lemon vinaigrette
- Steamed green beans with garlic
- Roasted asparagus with olive oil and lemon zest
Time-saving hacks:
- Use pre-cooked bacon crumbles (not quite as good, but it works)
- Use bagged shredded cheese and rotisserie chicken
- Prep everything in the morning and toss it in the oven after work
Leftovers and Storage
This casserole holds up like a champ.
- Fridge: Store in an airtight container for up to 3–4 days.
- Reheat: Microwave for 1–2 minutes or oven at 350°F until warmed through.
- Freeze: Portion it out and freeze. It reheats well—just let it thaw first for best texture.
If it dries out a little when reheating, just add a splash of milk or broth before microwaving.
FAQ
Can I make this without the bacon?
You can, but why would you? (Kidding. Kinda.) Just leave it out or use turkey bacon.
What if I don’t like ranch?
Try a packet of onion soup mix instead. Totally different vibe, but also delicious.
Can I use leftover pasta?
Yep! Just make sure it’s not overcooked. If it’s already soft, reduce baking time and go heavy on the sauce.
What cheese works best?
Sharp cheddar is my top pick. But feel free to play. Just avoid super soft cheeses like brie or goat here—it won’t work the same way.
Can I halve the recipe?
Totally. Use an 8×8 dish and cut everything in half. Bake time might be a few minutes shorter, so keep an eye on it.
