Ingredients for grandma's restaurant chicken tetrazzini
Sixteen ingredients transform into a nostalgic, restaurant-style comfort dish with crispy celery crowns and velvety bacon sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breasts 🍗 | 2 ½ lb | Pounded to even thickness |
| Fettuccine Pasta 🍝 | 12 oz | Al dente preferred |
| Celery Stalks 🧅 | 4 whole | Thinly sliced into crowns |
| Thick-Cut Bacon 🥓 | 8 oz | Cuts into lardons |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for richness |
| Chicken Broth 💧 | 1 ½ cups | Low-sodium preferred |
| Dry Sherry 🍷 | ¼ cup | Or substitute white wine |
| Grated Parmesan Cheese 🧀 | ½ cup | Freshly grated from block |
| Butter 🧈 | 4 tbsp | Unsalted, for crisping celery |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Fresh Thyme Leaves 🌿 | ¼ cup | Or 1 tsp dried thyme |
The celery crowns are the showstopper—thinly sliced celery stalks (about 1/4-inch thick) caramelize beautifully when cooked in butter. Look for crisp, firm celery with no browning at the base, and slice them uniformly for even cooking. I grab the pre-washed celery from Trader Joe's for convenience, but any quality grocery store brand works. For extra crunch, slice the celery just before cooking—it loses crispness quickly. The bacon should be thick-cut; Oscar Mayer or Applewood smoked are my go-tos, but any good-quality bacon will work. Cut it into 1/2-inch lardons for maximum crispiness and flavor infusion into the sauce.
No sherry? Dry white wine or extra chicken broth works perfectly—just reduce the amount slightly to avoid over-diluting the sauce. Fresh thyme is ideal, but dried thyme at one-third the amount is a fine substitute if you're in a pinch. The Parmesan needs to be freshly grated from a block—pre-grated cheese gets clumpy and lacks the same depth of flavor. For the chicken, boneless, skinless breasts are easiest, but thighs would add more richness. Pound them to an even thickness (about 1/4-inch) so they cook uniformly. If you're short on time, rotisserie chicken works in a bind—just shred it finely.
This dish reheats beautifully—honestly tastes better the next day once everything melds together. Store leftovers in an airtight container in the fridge for up to 4 days, or freeze for 3 months. I like to portion mine into individual containers before freezing so I can grab and reheat just what I need. The celery crowns crisp up again when reheated, so don't skip that final step. For serving, keep the garlic bread warm and the salad chilled—it balances the richness perfectly. The sauce thickens as it cools, so you can always thin it with a splash of warm milk or broth if needed.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this—just toss everything in one skillet. The bacon renders while you chop, the chicken cooks in its own juices, and the pasta absorbs that rich, savory sauce like a dream. No dirty dishes, no stress.
- Creamy Crisp Contrast: That crispy bacon crunch against the velvety mushroom sauce? It’s the kind of bite that makes you pause mid-bite. The chicken stays juicy, the celery adds a bright crunch, and the onion? It caramelizes just enough to deepen the flavor without overpowering.
- Weeknight Workhorse: Make a double batch on Sunday—it reheats like a champ for lunches all week. Or serve it at a potluck when you want to bring something hearty but still feel like you’ve put in effort. (Between us, no one will guess it’s this easy.)
- Budget-Friendly Feast: Chicken breasts and bacon stretch further than you’d think when paired with pasta. Plus, the onion and celery bulk it up so you’re not just serving sauce. Honestly, I’ve fed six people for under $15 with this—no one leaves hungry.
Step-by-step instructions for Grandma's restaurant chicken tetrazzini
Here's how to recreate Grandma's legendary dish with rich, creamy layers and perfectly crispy celery crowns.
Cook the Chicken and Prepare the Celery Crowns
Season the 2.5 lb boneless, skinless chicken breasts with 1 tsp of the 1.5 tsp salt and ¼ tsp of the 0.5 tsp black pepper. Heat 1 tbsp of the 4 tbsp butter in a large skillet over medium-high heat. Cook the chicken for 5-6 minutes per side until the internal temperature reaches 165°F and the juices run clear. Remove from heat and let rest for 10 minutes before slicing into ½-inch thick strips.
While the chicken cooks, slice the 4 whole celery stalks into thin, even crowns. Melt the remaining 3 tbsp butter in a separate skillet over medium heat. Add the celery and cook for 8-10 minutes, stirring occasionally, until golden brown and crispy. Remove and set aside on a paper towel-lined plate to drain excess butter.
Cook the Bacon and Build the Sauce Base
Cut the 8 oz thick-cut bacon into ¼-inch lardons. Cook in the same skillet used for the celery (no need to clean it—the fond adds flavor) over medium heat for 6-8 minutes until crispy and golden. Use a slotted spoon to remove the bacon and set aside on paper towels, leaving the rendered fat in the skillet.
Reduce heat to medium-low and add the diced 1 whole yellow onion. Cook for 5 minutes until softened. Add the minced 4 cloves garlic and cook for 30 seconds until fragrant. Pour in the 0.25 cup dry sherry and let it simmer for 2 minutes to cook off the alcohol. Stir in the 2 tbsp all-purpose flour and cook for 1 minute to create a roux.
Create the Creamy Sauce
Slowly whisk in the 1.5 cups heavy cream and 1.5 cups chicken broth, ensuring no lumps form. Add the remaining ½ tsp salt and ¼ tsp black pepper. Bring to a gentle simmer and cook for 5-7 minutes until the sauce thickens enough to coat the back of a spoon. Stir in the 0.25 cup fresh thyme leaves and 0.5 cup grated parmesan cheese, letting them melt into the sauce.
Return the crispy bacon to the skillet and stir to combine. Taste and adjust seasoning if needed—Grandma always said the sauce should be rich but not overpowering. Keep the sauce warm over low heat while you prepare the pasta.
Assemble and Bake the Tetrazzini
Cook the 12 oz fettuccine pasta according to package directions until al dente. Drain and toss immediately with 1 tbsp of the reserved pasta water to prevent sticking. In a large baking dish, layer half of the pasta, half of the sliced chicken, and half of the crispy celery crowns. Repeat with the remaining pasta, chicken, and celery.
Pour the warm sauce evenly over the top, pressing down gently to help it penetrate the layers. Sprinkle with additional 0.25 cup grated parmesan cheese if desired. Cover loosely with foil and bake at 375°F for 20 minutes. Uncover and bake for another 10-15 minutes until the top is golden brown and bubbly.
Rest and Serve
Remove from the oven and let rest for 5 minutes before serving. The dish should be bubbly with crispy celery crowns peeking through the creamy sauce. Serve immediately with a side of crusty bread to soak up every last bit of that rich, bacon-infused goodness.
This is where Grandma's secret comes into play—don't skip the crispy celery. Those golden crowns add texture that makes this dish truly special. The sauce should be thick enough to cling to every strand of pasta but still silky smooth. Enjoy the restaurant-quality meal you've just created at home!
Pro Tips For Making Grandma'S Restaurant Chicken Tetrazzini
- Cook Bacon First: I learned this the hard way—rushing the bacon in the same pot as the chicken and veggies just makes everything greasy. Crisp the bacon until it’s deep golden, then pull it out and set it aside. That rendered fat becomes your flavor base, and you won’t regret taking the extra 3 minutes.
- Slice Chicken Thin: Chicken breasts stay dry and tough if you cut them thick. Aim for ½-inch slices—no thicker—so they cook through without turning rubbery. If they’re still pink in the middle, you’ve gone too fast; slow it down.
- Don’t Overcook the Celery: Celery turns to mush if you let it simmer too long. Add it after the onions are soft but still bright, and keep the heat medium. You want it tender-crisp, not a sad, limp pile at the bottom of the pot.
- Deglaze with Broth: After browning the chicken and bacon, don’t just splash in water—use ½ cup chicken broth instead. It adds depth, and you’ll taste the difference. Scrape up every last bit of browned bits while you’re at it.
Wine and beer pairings for grandma's restaurant chicken tetrazzini
Classic White Wine
A crisp, dry Chardonnay from California or a Sauvignon Blanc from New Zealand complements the creamy richness of this dish beautifully. The bright acidity cuts through the bacon fat while enhancing the thyme and celery flavors.
I always reach for a La Crema Chardonnay—its subtle vanilla notes pair perfectly with the buttery sauce. 🍷
Rich Red Options
For those who prefer red wine, a Pinot Noir from Oregon offers enough elegance to stand up to the dish without overpowering it. Look for one with earthy undertones like Domaine Serene Pinot Noir—it mirrors the thyme and bacon while adding a touch of sophistication.
Avoid heavy Cabernets that would clash with the delicate celery crowns.
Light Beer Pairings
A wheat beer like Blue Moon or a Belgian witbier such as Hoegaarden provides refreshing contrast to the richness. The citrusy notes in these beers cleanse your palate between bites of creamy tetrazzini.
For a heavier option, try a light lager like Heineken—its crispness balances the dish's decadence without competing. 🍺
Non-Alcoholic Choices
For non-drinkers, a sparkling apple cider like Martinelli's adds festive bubbles that mimic wine's acidity. Alternatively, ginger beer provides a zesty kick that cuts through the creaminess. I've also found that sparkling water with lemon works surprisingly well—just add a splash of grenadine for color and a touch of sweetness.
Dessert Wine Finish
If you're serving this as a main course followed by dessert, consider a Moscato d'Asti or Riesling for a sweet finish. The slight sweetness complements the dish's savory notes while preparing your palate for something richer. A chilled Prosecco also works beautifully for a celebratory touch. 🥂

Frequently asked questions
Can I make this Chicken Tetrazzini without bacon?
Swap the bacon for 8 oz of thick-cut ham diced into lardons or use 1 cup of crispy fried shallots for flavor and texture. For a vegetarian version, try sautéing 1 cup of mushrooms or sun-dried tomatoes in olive oil instead. The key is maintaining that crispy element to balance the creamy sauce.
How do I keep the celery crowns crispy after baking?
Cook the celery crowns just until golden (8-10 minutes) and drain them well on paper towels before adding to the dish. When assembling, place them on top of the pasta layer rather than mixing them in—this lets them stay crispy even after baking. If they soften during baking, broil for 2-3 minutes at the end to restore crispness.
What's the secret to making the sauce extra creamy?
Use full-fat heavy cream (not light cream) and let the sauce simmer gently for 5-7 minutes to thicken properly. For extra richness, stir in 2 tbsp of cold butter at the end. Also, make sure your roux (flour + fat) is cooked for 1 full minute to remove the raw flour taste—this prevents a grainy texture.
Can I make this ahead of time?
This dish actually tastes better the next day! Assemble it completely (including sauce) and refrigerate uncovered for 4-6 hours to let flavors meld. Bake straight from the fridge at 375°F for 30-35 minutes, adding 1-2 tbsp of water or broth if the sauce seems too thick. For freezing, assemble and bake, then cool completely before storing in airtight containers for up to 3 months.
What pasta works best besides fettuccine?
Penne or rigatoni work beautifully—their ridges help hold the creamy sauce. For a lighter option, try angel hair pasta, but you'll need to reduce the sauce slightly. Avoid long, thin pastas like spaghetti—they won't hold up well in the baking process. If using a different shape, cook it 1 minute less than package instructions for better texture.
