When the Instant Pot lid comes off, the onions underneath the turkey have softened into the start of a gravy, and the broth smells rich with thyme. That’s the part I like about this Instant Pot Turkey Breast with Onion Gravy: the turkey cooks above the onions, so the same pot gives you tender slices and a savory base for the sauce. There’s no roasting pan to scrub or separate pot of gravy to build.
The timing is set for one fully thawed, 4-pound, bone-in turkey breast in a 6-quart Instant Pot. I pat the skin dry, season the whole breast, and let the onions turn lightly golden before adding broth. That short sauté gives the gravy a sweeter, deeper onion flavor than pressure-cooking raw onions from the start. The finished turkey is rested before carving, then served with a thick, thyme-scented gravy that clings to each slice.
Kitchen Note
The 30-minute pressure cook is for a fully thawed, 4-pound bone-in breast. Don’t put a frozen breast in and expect the same timing to work; thaw it completely before seasoning.
Save this Instant Pot turkey breast with onion gravy for tender slices and a savory, thyme-scented sauce made in the same pot.
Why the skin-on turkey breast won’t come out crisp in the Instant Pot
A pressure cooker is a moist, enclosed cooking environment, not a dry oven. The breast sits skin-side up on a trivet above the broth and onions, but the trapped steam means the skin won’t turn crisp. I keep it on during cooking because that’s how this recipe is designed; after carving, you can leave it on the slices or remove it at the table. If crisp skin is your main goal, this isn’t the method to choose.
What you get instead is a tender turkey breast and a pot liquid that already has the makings of gravy. The onions soften in butter first, then cook with broth and thyme beneath the turkey. Their sweetness carries into the sauce, while the flour slurry thickens that savory liquid without needing a separate roux. Think of it as a pressure-cooked turkey dinner with a built-in onion gravy, not roast turkey with crisp skin and pan drippings. The trade-off is clear: soft skin, less hands-on cooking, and gravy that tastes connected to the turkey.
The onion, broth, and flour that turn pot liquid into gravy
- Bone-in, skin-on turkey breast — The 4-pound size and bone-in cut are what the pressure-cooking timing is built around. Choose a fully thawed breast; there’s no dependable one-for-one swap to a small boneless cut because it cooks differently. A standard grocery-store turkey breast is fine, and patting the skin dry before seasoning helps the salt and pepper coat it evenly.
- Yellow onions — They soften into the gravy and bring a rounded sweetness that sharper onions won’t quite match. There’s no need to seek out specialty onions; choose firm ones and slice them thinly so they soften evenly in the sauté stage. White onions can stand in in the same quantity, though the gravy will taste a little sharper.
- Low-sodium chicken broth — The broth carries the onion and thyme flavors and becomes the liquid for the gravy. A basic carton works well; low-sodium gives you better control over the finished seasoning as the liquid simmers. Regular broth will work, but it can leave the gravy saltier.
- Unsalted butter — Butter gives the onions a gentle richness as they soften. An everyday brand is all you need; using unsalted butter keeps the recipe’s added salt from being harder to control.
- All-purpose flour — Whisking flour with cool broth before it goes into the pot makes a smooth slurry and thickens the cooking liquid into gravy. Regular all-purpose flour is the straightforward choice here; there’s no benefit to using a specialty flour unless you need a dietary adaptation.
- Dried thyme — Dried thyme holds its herbal flavor through pressure cooking and gives the onion gravy a savory note without taking over. Keep it with the onions and broth so it has time to infuse the pot liquid.
From lightly golden onions to gravy without a raw-flour taste
Season the breast evenly
Pat the fully thawed turkey breast dry, then season all over with kosher salt and black pepper. Get seasoning across the top, sides, and underside rather than leaving the underside bare. Set the breast aside while you build the onion base.
Soften the onions before pressure cooking
Set a 6-quart Instant Pot to Sauté and melt the butter. Add the thinly sliced onions and cook for 6–8 minutes, stirring often, until they’re softened and lightly golden. If they’re still firm or pale, give them the full time they need; this brief sauté is where their sweetness develops. Pour in 1 cup of the broth and add the dried thyme, then scrape the bottom of the pot to loosen any browned bits.
Pressure-cook, then check the thickest part
Set the trivet over the onions and broth, then place the turkey on it skin-side up. Lock the lid with the valve set to Sealing and cook at High Pressure for 30 minutes. Let the pressure release naturally for 10 minutes, then carefully quick-release what remains. Check the thickest part of the breast, away from the bone, for 165°F; if it’s below that, reseal and cook at High Pressure for 3 minutes, let the pressure release naturally for 5 minutes, and check again.
Give the turkey time to rest
Transfer the turkey to a cutting board and let it rest for 15 minutes before carving. Use that time to finish the gravy rather than cutting into the breast straight away. The rest gives you a calmer carving window and keeps the slices easier to handle.
Thicken the onion gravy in the pot
Whisk the remaining 1/2 cup broth with the flour until the mixture is smooth. Set the Instant Pot to Sauté and whisk the slurry into the onions and pot liquid. Simmer for 3–5 minutes, whisking often, until the gravy thickens and no longer tastes of raw flour. Spoon it over the carved turkey while it’s warm.
How to make the onion gravy gluten-free, dairy-free, or more herb-forward
Use a gluten-free flour blend
Replace the all-purpose flour with the same amount of a cup-for-cup gluten-free flour blend intended as a 1:1 baking substitute. Whisk it into the broth until smooth before adding it to the pot; the gravy may have a slightly different texture depending on the blend, but it will still thicken the onion liquid.
Make the onion base dairy-free
Use the same amount of plant-based butter in place of the unsalted butter. The onions will still soften in the sauté stage, though the gravy may taste a little less buttery. Keep the rest of the method the same.
Give the gravy a sage note
Swap the dried thyme for half as much dried sage. Sage is more assertive, so this smaller amount keeps the herb from crowding out the onions. Add it with the broth before pressure cooking.
Storage and Reheating
- Refrigerator: Store the carved turkey and gravy in separate airtight containers for 3–4 days. The gravy will firm up as it chills.
- Freezer: Freeze turkey slices and gravy separately in airtight freezer-safe containers for up to 2–3 months. The gravy may need a good whisk after thawing.
- Reheating: Warm the turkey gently with gravy spooned over the slices, and reheat leftovers to 165°F. Warm gravy separately, whisking as it heats; high heat can dry out the turkey before the gravy is ready.
