Keto Slow Cooker Chicken with Creamy Tomato & Spinach
I first tried this Keto Slow Cooker Chicken with Creamy Tomato & Spinach on a busy weeknight and it instantly became a go-to—rich, velvety sauce, tender chicken, and a pop of sun-dried tomato that keeps every bite interesting. It’s the kind of slow-cooker dinner that feels indulgent but stays low-carb, and it pairs especially well with zoodles when you want to skip the starch. If you like slow-cooked, saucy chicken recipes (think a mash-up of comfort food and light Mediterranean flavors), this one will fit right into your rotation—similar in spirit to my favorite creamy tomato basil chicken but with Asiago and spinach for extra depth.
Why you’ll love this dish
This recipe hits several sweet spots: minimal hands-on time, pantry-friendly ingredients, and a creamy finish that feels restaurant-style without the fuss. It’s perfect for weeknights, meal-prep Sundays, or when you want an impressive dish with almost zero babysitting. The sun-dried tomatoes bring concentrated sweetness and umami, while Asiago adds a sharper, nuttier cheese note than mozzarella would.
“A velvety, low-carb crowd-pleaser—makes the whole house smell amazing and reheats like a dream.”
If you like hearty slow-cooker meals such as chicken cacciatore with potatoes, this recipe is a great low-carb companion that still delivers big flavor.

What you’ll need
- 2 lbs boneless, skinless chicken breasts (trim excess fat; halve large breasts if desired)
- 1/2 cup sun-dried tomatoes, chopped (oil-packed or dry—see substitutions below)
- 1 cup chicken broth (low-sodium preferred)
- 1/2 teaspoon Italian seasoning
- 2 cloves garlic, crushed or minced
- 4 oz cream cheese, cut into cubes and softened slightly
- 1/2 cup Asiago cheese, shredded (freshly shredded melts better)
- 8 oz raw baby spinach, roughly chopped
Substitutions and notes:
- Oil-packed sun-dried tomatoes add richness; if using dry-packed, rehydrate quickly in warm water or use an extra tablespoon of olive oil.
- Asiago can be swapped for Parmesan or Pecorino for a saltier bite, but reduce added salt.
Step-by-step instructions
- Add sun-dried tomatoes, chicken broth, crushed garlic, and Italian seasoning to the slow cooker. Stir to combine.
- Place the chicken breasts on top of the tomato mixture. If breasts are very large, halve them so they cook evenly.
- Cover and cook on HIGH for 3½ hours (or LOW for about 6–7 hours) until the chicken is cooked through and tender.
- Remove the chicken to a plate and cover to keep warm.
- Add the cubed cream cheese and shredded Asiago to the slow cooker. Cover and cook for 5 minutes to soften the cheeses.
- Remove the lid and whisk until the sauce is smooth and creamy. If needed, use a handheld immersion blender briefly for extra silkiness.
- Stir in the chopped spinach, cover, and cook for 10 more minutes until the spinach is wilted and fully incorporated.
- Return the chicken to the slow cooker or place it on a platter and spoon the sauce over top. Serve immediately over your chosen base.
If you like finger foods alongside slow-cooker mains, this method matches well with lighter appetizers like cheesy jalapeño ranch chicken poppers for game-day spreads.
Best ways to enjoy it
- Low-carb: Serve over zucchini noodles (zoodles) for a lighter plate that soaks up the sauce.
- Classic comfort: Spoon over cauliflower rice for extra volume without carbs.
- Treat it like a weeknight dinner: Plate with a small mound of buttered pasta or rice if you’re not watching carbs—this sauce is rich enough to feel special.
- Garnish ideas: A drizzle of extra-virgin olive oil, chopped fresh basil, or a sprinkle of cracked black pepper and lemon zest brightens the dish.
Storage and reheating tips
- Refrigeration: Store leftovers in an airtight container for up to 3–4 days. Cool to room temperature for no more than 2 hours before refrigerating.
- Reheating: Reheat gently on the stovetop over low heat, stirring occasionally until warmed through; add a splash of broth or water if the sauce thickened too much. Microwave in 30-second increments, stirring between bursts.
- Freezing: Freeze sauce and chicken in an airtight container for up to 3 months. Thaw overnight in the fridge before reheating. Note: cream-based sauces sometimes separate after freezing; whisking vigorously or warming slowly on the stove restores texture.
- Food safety: Ensure chicken reheats to an internal temperature of 165°F (74°C) before serving.
Pro chef tips
- Soften the cream cheese slightly before adding; that helps it melt smoothly into the sauce.
- Freshly shred Asiago instead of pre-shredded: pre-shredded cheese often contains anti-caking agents that prevent it from melting as well.
- For a silkier sauce, whisk or briefly use an immersion blender after cheese melts. Don’t over-blend—leave some texture from the tomatoes.
- If your sauce is too thick, thin it with extra chicken broth, a splash of cream, or reserved pasta water if serving over starch.
- To amp up flavor, sauté the garlic and sun-dried tomatoes in a skillet with a tablespoon of olive oil before adding to the slow cooker—this unlocks more aroma.
Creative twists
- Mediterranean: Add kalamata olives and a squeeze of lemon before serving.
- Spicy kick: Stir in red pepper flakes or a teaspoon of harissa for heat.
- Keto-friendly creamier: Swap Asiago for a mix of cream cheese and heavy cream for an ultra-luxurious texture.
- Veg-forward: Toss in sliced mushrooms or bell peppers with the tomatoes for extra body.
- Protein swap: Use boneless skinless thighs for richer, more forgiving meat that stays juicy if you cook longer.
Your questions answered
Q: Can I use frozen chicken breasts?
A: Yes—use frozen only if your slow cooker has a manual that allows cooking from frozen. For food safety and even cooking, it’s best to thaw first. If you cook from frozen, increase cooking time and ensure the internal temperature reaches 165°F (74°C).
Q: Is this recipe keto-friendly?
A: Yes. The sauce is low in carbs thanks to sun-dried tomatoes in moderation, spinach, cream cheese, and Asiago. Serve over zoodles or cauliflower rice to keep it keto.
Q: Can I make this dairy-free?
A: For a dairy-free version, omit cream cheese and Asiago. Replace with a can of full-fat coconut milk and 2–3 tablespoons of nutritional yeast for savory depth; flavor and texture will be different but still tasty.
Q: How can I thicken the sauce if it’s too thin?
A: Simmer uncovered for 10–15 minutes to reduce it, or whisk in a tablespoon of xanthan gum slowly (a small amount goes a long way for low-carb thickening).
Q: Can I double the recipe?
A: You can, but ensure your slow cooker isn’t packed more than two-thirds full so food cooks evenly. You may need to extend cooking time slightly.
