Ingredients

  

• 2 to 2.5 pounds boneless, skinless chicken breasts or thighs
• 1 (14–15 oz) can crushed tomatoes (no sugar added)
• 1/3 cup oil-packed sun-dried tomatoes, drained and chopped
• 1/2 medium yellow onion, finely chopped
• 3–4 garlic cloves, minced
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 1/2 teaspoon dried thyme
• 1/2 teaspoon red pepper flakes (optional, for heat)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1/2 cup chicken broth (preferably low-sodium)
• 4 ounces cream cheese, cut into cubes and softened
• 1/2 cup heavy cream
• 2 tablespoons extra-virgin olive oil
• 1/2 cup grated Parmesan cheese, plus more for serving
• Fresh basil or parsley, chopped (for garnish)
• Optional add-ins: 2 cups baby spinach, 8 oz sliced mushrooms, or 1/3 cup pitted black olives
• For serving: Zucchini noodles, cauliflower rice, spaghetti squash, or sautéed greens

Method

 

1. Prep the slow cooker base: Add crushed tomatoes, sun-dried tomatoes, onion, garlic, oregano, basil, thyme, red pepper flakes, salt, black pepper, and chicken broth to the slow cooker. Stir to combine.
2. Season the chicken: Pat the chicken dry and season both sides with a pinch of salt and pepper. Nestle the pieces into the sauce in an even layer.
3. Drizzle with olive oil: Pour the olive oil over the top to help carry flavor and keep the chicken moist.
4. Slow cook: Cover and cook on Low for 4–5 hours or on High for 2–3 hours, until the chicken is tender and reaches 165°F internally. Thighs may need a little longer than breasts.
5. Shred or slice: Remove the chicken to a plate. Shred with two forks or slice into thick pieces, then return it to the slow cooker.
6. Make it creamy: Stir in the cream cheese until melted and smooth. Pour in the heavy cream and mix well. Add Parmesan and stir until the sauce is creamy and cohesive.
7. Add extras (optional): If using spinach or mushrooms, stir them in now. Cover and cook on Low for 10–15 more minutes, just until the greens wilt or mushrooms soften.
8. Taste and adjust: Taste the sauce. Add more salt, pepper, or red pepper flakes if needed. If it’s too tangy, a pinch of erythritol or monk fruit sweetener can balance the acidity without adding carbs.
9. Serve: Spoon the chicken and sauce over zucchini noodles, spaghetti squash, or cauliflower rice. Finish with fresh basil or parsley and extra Parmesan.

  The flavors deepen by day two.

• Freezer: Freeze in portions for up to 3 months. Thaw overnight in the fridge, then reheat gently.
• Reheating: Warm on the stovetop over low heat or in the microwave at 50% power. Add a splash of cream or broth if the sauce thickens too much.

Benefits of This Recipe

• Keto-friendly and satisfying: High in protein and healthy fats to keep you full longer.
• Budget-conscious: Uses pantry staples and turns inexpensive chicken into a hearty, flavorful dinner.

What Not to Do

• Don’t overcook the chicken: Even in a slow cooker, chicken can dry out.

  Check for doneness around the earliest time.

• Don’t add dairy too early: Cream cheese and cream can split if cooked for hours. Stir them in at the end.
• Don’t skip seasoning: Taste and adjust salt and acidity. Tomatoes vary—balance is key.
• Don’t use sugary sauces: Avoid jarred sauces with added sugar.

  Stick to no-sugar-added tomatoes.

• Don’t overcrowd add-ins: Too many veggies can water down the sauce. Add moderately.

Alternatives

• Protein swaps: Try boneless, skinless turkey breast or pork tenderloin cut into large chunks. Adjust cook times as needed.
• Dairy-free option: Use full-fat coconut cream instead of heavy cream and skip Parmesan.

  Add nutritional yeast for a cheesy note.

• Spice variation: Swap oregano and basil for Italian seasoning, or add a pinch of fennel seed for a sausage-like depth.
• Tomato variation: Replace crushed tomatoes with fire-roasted diced tomatoes for a smokier flavor. Blend for a smoother sauce.
• Vegetable base: Serve over sautéed cabbage ribbons, roasted broccoli, or a bed of baby arugula for freshness.

FAQ

Can I make this with frozen chicken?

It’s best to use thawed chicken for food safety and even cooking. If your chicken is frozen, thaw it in the refrigerator overnight before starting.

How do I thicken the sauce without flour?

The cream cheese, Parmesan, and reduction from cooking naturally thicken the sauce.

If you need it thicker, remove the lid and let it simmer on High for 15–20 minutes, or stir in a bit more Parmesan.

Breasts or thighs—what’s better?

Both work. Thighs are more forgiving and stay juicier, while breasts are leaner. If using breasts, monitor the time closely to avoid drying out.

Is this spicy?

Only if you add red pepper flakes.

Start with a small pinch and adjust to taste. You can leave them out entirely for a milder sauce.

Can I cook this on the stovetop?

Yes. Simmer the sauce in a large skillet, add seasoned chicken, cover, and cook over low heat until done (about 15–20 minutes for breasts).

Stir in the dairy at the end.

What sides go best with this?

Zucchini noodles, cauliflower rice, spaghetti squash, roasted asparagus, or a simple green salad all pair well and keep it keto.

How can I reduce the carbs even more?

Use fewer sun-dried tomatoes and choose the lowest-carb canned tomatoes available. Skip onion or reduce the amount, and avoid sweeteners unless needed for balance.

Can I make it ahead?

Absolutely. Assemble the sauce and chicken in the slow cooker insert the night before and refrigerate.

In the morning, place the insert in the cooker and start. Add dairy at the end as directed.
