Chicken Tetrazzini Betty Crocker Recipe: Creamy Celery and Mushroom One-Pan Masterpiece

Betty Crocker’s Chicken Tetrazzini recipe delivers that creamy, comforting one-pan masterpiece we all crave when craving a restaurant-quality meal at home. Growing up in small-town Georgia, I remember my grandmother’s version—how the celery and mushrooms transformed simple chicken into something luxurious.

This classic dish proves that foolproof techniques can yield restaurant-worthy results without the fuss.

The secret lies in the sauce—a rich blend of cream, cheese, and herbs that coats every bite of tender chicken and sautéed vegetables. Cooking time is minimal (30–40 minutes at 350°F), making it perfect for weeknight dinners when you want something hearty but don’t have hours to spare.

The dish bakes in one pan, so cleanup is effortless, and the aroma alone will have everyone gathering around the table.

What you’ll end up with is a creamy, velvety casserole where each layer—golden chicken, tender mushrooms, and crisp celery—melts into the sauce with every bite. The texture is impossible to resist: tender chicken, al dente pasta, and a sauce so rich it clings to every forkful.

This is the kind of dish that turns a simple dinner into a memorable meal, and it’s easier to make than you’d think.

Pair it with garlic bread and a fresh salad for a complete, satisfying meal. The original recipe includes dairy and eggs, but I’ll show you how to adapt it for dietary preferences without sacrificing flavor. Let’s get started on this one-pan classic that’s been comforting families for decades.

Ingredients for chicken tetrazzini betty crocker

Creamy, comforting, and packed with savory layers—this classic one-pan dish delivers restaurant-quality flavor at home.

The chicken is the foundation, so don't skimp on quality. Boneless, skinless breasts work best—cut them into even pieces so they cook uniformly. I always grab mine from Costco when I'm doing a big batch, but the regular supermarket stuff works fine for a weeknight dinner. For the mushrooms, cremini or button types hold up best during baking, but wild mushrooms add gourmet flair if you're feeling fancy. The celery and onion? Fresh and crisp—no wilting or bruising. If you're prepping ahead, store them separately in airtight containers for up to 3 days.

No heavy cream? Half-and-half or whole milk with an extra tablespoon of butter works in a pinch, though the texture won't be quite as luscious. The cheeses are non-negotiable—sharp cheddar and freshly grated Parmesan give that authentic Tetrazzini bite. Pre-shredded cheese gets clumpy, so grate your own from a block if you can. For the herbs, fresh parsley is ideal but dried thyme at half the amount gets you close. The flour is just for thickening—don't skip it, but don't overdo it either. And if you're watching calories, light cream cheese can replace half the cheddar without sacrificing flavor.

This dish reheats beautifully—honestly tastes better the next day once everything melds together. Keeps in the fridge for 4-5 days, though I usually eat it within 2 days. For leftovers, portion into individual containers so lunches are sorted for the week. Freezes for 3 months if sealed tightly in a freezer bag. Pro tip: Sprinkle a little extra Parmesan on top before baking—it gets crispy and adds that restaurant-quality finish.

Step-by-step instructions for creamy chicken Tetrazzini

Here's how to craft this rich, one-pan masterpiece with tender chicken and velvety mushroom sauce.

Cut the 1.5 lb boneless, skinless chicken breast into 1-inch bite-sized pieces and set aside. In a large oven-safe skillet, melt the 0.5 cup butter over medium heat until it foams. Add the 1 whole yellow onion and 2 whole celery stalks, both diced, cooking for 5 minutes until softened and translucent.

Stir in the 8 oz sliced white mushrooms and cook for another 6-8 minutes until they release their moisture and begin to brown. Add the 3 minced garlic cloves and 0.5 tsp dried thyme, cooking for 30 seconds until fragrant. This aromatic base forms the flavor backbone of your dish.

Sprinkle the 2 tbsp all-purpose flour over the vegetable mixture and stir vigorously for 1-2 minutes to cook out the raw flour taste. Slowly pour in the 1 cup heavy cream, whisking constantly to prevent lumps. Let the sauce simmer for 3-4 minutes until it thickens enough to coat the back of a spoon.

Reduce heat to low and add the 1 cup shredded cheddar cheese and 0.5 cup freshly grated parmesan cheese, stirring until completely melted and smooth. Season with 1 tsp salt and 0.5 tsp black pepper, then remove from heat. This creamy mixture is where all the magic happens—don't rush this step.

Increase heat to medium-high and add the chicken pieces, cooking for 5-6 minutes until they're just cooked through (they'll finish cooking in the oven). Remove the chicken with a slotted spoon and set aside. Add the 8 oz uncooked fettuccine pasta to the skillet, tossing to coat it completely in the sauce.

Return the chicken to the skillet and stir gently to combine. The pasta will absorb the creamy sauce as it cooks. Cover the skillet and let it sit off heat for 5 minutes to allow the pasta to begin cooking in the residual heat.

Preheat your oven to 375°F. Transfer the skillet to the oven and bake uncovered for 15-18 minutes until the pasta is tender and the top is lightly golden. If the sauce looks too thick, add 2-3 tablespoons of water during baking to achieve that perfect creamy consistency.

Remove from the oven and let it rest for 2-3 minutes. Garnish with 0.25 cup chopped fresh parsley before serving. The dish should be bubbly, creamy, and perfectly al dente—each bite delivering tender chicken, rich mushroom sauce, and perfectly cooked pasta.

Health benefits of this dish

Protein Powerhouse

This dish delivers a solid 30 grams of protein per serving—thanks to the chicken and cheese combo. The 1.5 lb boneless, skinless chicken breast provides lean protein that keeps you full and energized, while the 1.5 cups of cheese add extra staying power.

I’ve served this to my crew after long shifts at The Smoky Pig, and they always ask for seconds. 💪

Creamy Comfort Nutrition

The heavy cream and cheese make this dish rich and satisfying, but they also provide essential nutrients. One serving contains about 25% of your daily calcium needs from the cheeses, plus 10% of your vitamin D—both crucial for bone health.

The mushrooms add selenium, an antioxidant that supports your immune system.

Fiber Boost from Veggies

Don’t overlook the celery and mushrooms—they pack 3 grams of fiber per serving, helping digestion and keeping you full longer. I always double-check that the celery is fresh and crisp, as it adds that satisfying crunch and nutritional value.

The onions contribute quercetin, a compound that fights inflammation, making this more than just comfort food. 🥕

Balanced Meal Structure

This one-pan wonder combines protein, healthy fats, and complex carbs from the pasta, creating a balanced meal. The fettuccine provides energy-sustaining carbs, while the butter and cream offer flavorful fats that aid nutrient absorption. It’s the kind of meal that keeps energy steady without the crash of refined carbs alone.

Dietary Adaptations

For a lighter version, swap the heavy cream for Greek yogurt or light cream cheese, cutting calories while keeping richness. If you’re watching fat, use part-skim mozzarella instead of sharp cheddar.

The dish still delivers comfort without the guilt. I’ve even made a gluten-free version with chickpea pasta for friends with dietary restrictions—it works surprisingly well. 💡

Meal Prep Advantage

Leftovers reheat beautifully, making this a great make-ahead meal. The flavors deepen overnight, and the creamy sauce reheats smoothly. I always portion mine into airtight containers for easy grab-and-go lunches. The protein and fiber combo keeps you satisfied through busy workdays—perfect for my team at the restaurant. ❄️
