The 3-Phase Simmer: in practice
Ingredients for Low-Carb Success
Trading traditional pasta for low-carb vegetables is the secret to a lighter bowl. Use radishes or turnips instead of potatoes for a similar texture with fewer carbs.
Choose high-quality bone broth to add 10 grams of protein per serving. This keeps you full for longer without needing heavy starches.
- Use 2 cups of chopped radishes to replace potatoes.
- Swap pasta for 1 cup of cauliflower florets.
- Add 1 tbsp of tomato paste for depth.
Mastering the Slow Cooker Timing
The slow cooker is your best tool for developing complex flavors without constant heat. Set it to Low to keep vegetables from turning into mush over 8 hours.
Avoid overfilling the vessel. Keep ingredients at least 2 inches below the rim to ensure even heat distribution.
- Set timer for 6 hours on Low.
- Keep lid sealed to trap moisture.
- Check seasoning 30 minutes before serving.
Pairing with Air Fryer Sides
Since the soup takes hours, use your air fryer for a quick 10-minute side dish. Crispy parmesan crisps provide the perfect crunch to replace bread.
Air fry your side at 375°F for 5 minutes for golden results. This adds a texture contrast that makes the meal feel complete.
- Air fry pepperoni slices at 375°F for 4 minutes.
- Make parmesan crisps in 3 minutes.
- Toast almond flour crackers for 5 minutes.

Storage and Reheating Tips

- Freeze in 1-cup portions for 3 months.
- Thaw in the fridge for 24 hours.
- Refresh with fresh basil before serving.

Frequently asked questions
Can I use dry beans in the slow cooker?

How do I keep it low-carb?
Focus on fibrous greens and cruciferous vegetables. Skip the beans and pasta entirely to stay under 10g net carbs.
Is it safe to leave on while at work?
Yes, most modern slow cookers are designed for 8-10 hour cycles. Ensure your device is on a flat surface away from water.
Can I add meat?
Yes, brown 1 lb of Italian sausage or chicken thighs first. Add them to the pot to boost the protein content.
