Instant Pot creamy broccoli chicken is a one-pot, family-friendly meal that comes together quickly and delivers tender chicken, vibrant broccoli, and a rich, cheesy sauce. This recipe is perfect for busy weeknights or meal prep, and it uses only a handful of basic ingredients. The Instant Pot drastically reduces cooking time while locking in flavor and moisture, resulting in a dish that tastes like you spent all afternoon making it. Before you begin, make sure your Instant Pot is clean, you have all the ingredients on hand, and that you know how to safely use the appliance.
What You’ll Need
- 1.5 pounds boneless, skinless chicken breasts or thighs
- 4 cups fresh broccoli florets (about 1 medium head)
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 cup low-sodium chicken broth
- 1 cup heavy cream or half-and-half
- 1 cup shredded cheddar cheese (plus extra for topping, optional)
- 2 tablespoons cream cheese (optional, for extra creaminess)
- 2 tablespoons olive oil or butter
- 1 teaspoon kosher salt (adjust to taste)
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme or Italian seasoning (optional)
- 1 tablespoon cornstarch (for thickening, optional)
- Instant Pot or other electric pressure cooker
- Wooden spoon or spatula
- Cutting board and knife
- Measuring cups and spoons
Step-by-Step
- Prep the Ingredients: Cut chicken into bite-sized pieces or leave whole if you prefer shredding later. Chop broccoli into florets, dice the onion, and mince the garlic.
- Sauté Aromatics: Set the Instant Pot to “Sauté” mode. Add olive oil or butter. Once hot, add diced onion and cook for 2-3 minutes until softened. Stir in garlic and sauté for another 30 seconds, just until fragrant.
- Add Chicken: Place chicken pieces in the pot. Season with salt, pepper, and thyme or Italian seasoning if using. Sauté for 2-3 minutes, turning to lightly brown (the chicken will finish cooking under pressure).
- Deglaze: Pour in chicken broth. Use a wooden spoon to scrape up any browned bits from the bottom (this prevents the “burn” warning).
- Pressure Cook: Secure the lid and set the valve to “Sealing.” Pressure cook on High Pressure for 5 minutes (for bite-sized pieces) or 8 minutes (for whole breasts/thighs). It will take about 10 minutes to come to pressure.
- Quick Release: When the timer beeps, use a quick release (carefully turn the valve to “Venting”) to release steam. Once pressure is fully released, open the lid.
- Add Broccoli: Add broccoli florets and close the lid (no need to seal). Let sit for 3-5 minutes—the residual heat will steam the broccoli until just tender but still bright green. For very soft broccoli, use “Sauté” mode and stir for 2-3 minutes.
- Add Cream: Stir in heavy cream and cream cheese (if using). Mix until cream cheese is melted and sauce is smooth.
- Thicken the Sauce: For a thicker sauce, whisk 1 tablespoon cornstarch with 2 tablespoons cold water and stir into the pot. Set Instant Pot to “Sauté” and cook, stirring, for 1-2 minutes until thickened.
- Add Cheese: Turn off the heat. Stir in shredded cheddar cheese until melted and creamy. Taste and adjust seasoning if needed.
- Serve: Spoon creamy broccoli chicken into bowls. Top with extra cheese, cracked pepper, or fresh herbs if desired. Serve over rice, pasta, or with crusty bread.
Common Mistakes
- Overcooking the Broccoli: Adding broccoli before pressure cooking will result in mushy, discolored florets. Always add after pressure release.
- Burn Notice: Not deglazing the pot after sautéing chicken or onions can cause a burn warning. Always scrape up browned bits before sealing.
- Curdled Dairy: Adding cream or cheese before pressure cooking can cause separation. Only add creamy ingredients after the pressure cycle is done.
- Dry Chicken: Pressure cooking for too long, especially with chicken breast, can dry out the meat. Stick to the recommended times.
- Too Thin Sauce: Skipping the cornstarch slurry may leave the sauce watery, especially if using frozen broccoli or chicken.
Tips
- Chicken Cut: Thighs stay moister than breasts, but both work well. For shreddable chicken, use whole pieces and shred after pressure cooking.
- Cheese Variations: Try Monterey Jack, mozzarella, or a blend for different flavors. Add a little Parmesan for extra richness.
- Vegetable Boost: Add diced carrots, bell pepper, or peas with the onions for more color and nutrition.
- Make it Lighter: Use half-and-half or evaporated milk instead of heavy cream for a lighter sauce.
- Meal Prep: Store leftovers in airtight containers in the fridge for up to 3 days. Reheat gently to avoid sauce separation.
- Gluten-Free: This recipe is naturally gluten-free. Confirm your broth and cheese are certified if needed.
- Low-Carb Option: Serve over cauliflower rice or steamed veggies instead of grains.
- Batch Cooking: Double the recipe if your Instant Pot is 6 quarts or larger. Do not fill past the max fill line.
Troubleshooting
- Sauce Too Thin: Stir in a cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons cold water) and simmer on Sauté until thickened.
- Sauce Too Thick: Add a splash of chicken broth or milk until desired consistency is reached.
- Chicken Not Cooked Through: If chicken is underdone, return to the pot, seal, and cook on High Pressure for 2 more minutes, then quick release.
- Broccoli Too Firm: Turn on Sauté and cook, stirring, for 1-2 minutes until broccoli is just right.
- Burn Notice: Turn off the pot, open the lid, and scrape the bottom clean. Add a splash more broth, then resume cooking.
- Curdled Sauce: If the sauce separates, whisk vigorously off-heat and add a bit more cream or cheese to bring it back together. Avoid boiling after adding dairy.
Frequently Asked Questions
- Can I use frozen chicken or broccoli?
- Yes, but add 2-3 minutes to the pressure cook time for frozen chicken. Use frozen broccoli only after pressure cooking, as it softens quickly.
- Is this recipe keto-friendly?
- It can be! Use heavy cream, full-fat cheese, and serve over cauliflower rice or on its own to keep carbs low.
- How do I store and reheat leftovers?
- Store in airtight containers for up to 3 days in the fridge. Reheat gently on the stove or in the microwave, stirring to keep the sauce smooth.
- Can I make this dairy-free?
- Use a dairy-free cream (like coconut cream) and a plant-based cheese substitute. Flavor and texture will differ, but it still works.
- What if I don’t have an Instant Pot?
- You can make this on the stovetop: Sauté, simmer the chicken in broth until cooked, add broccoli, then finish with cream and cheese.
- Can I use other vegetables?
- Absolutely. Cauliflower, green beans, carrots, or peas all work well. Adjust cook times as needed to keep veggies crisp-tender.
