Reheating
To bring your Bolognese back to life:
Stovetop Method (Best for Creamy Texture):

- Add a splash of water, broth, or cream to loosen the sauce if needed.
- Stir occasionally until heated through.
Microwave Method (Quick and Easy):

- Microwave in 1-minute intervals, stirring in between, until heated through.

💭My Recipe Tips
- Prep Ahead: Chop your vegetables and measure your ingredients the night before to make morning prep a breeze.
- Brown the Meat (Optional): For extra flavor, brown the sausage and ground beef in a skillet before adding them to the slow cooker.
- Use Fresh Herbs: Fresh oregano adds a bright, herbaceous note, but if you only have dried, use 1 teaspoon instead of 1 tablespoon.
- Don’t Skip the Wine: The red wine adds depth and richness to the sauce. If you avoid alcohol, substitute with broth and a splash of balsamic vinegar.
- Layer the Meat: Break the sausage and ground beef into small pieces with your fingers as you add it to the slow cooker. This ensures even cooking and no large clumps.
- Skim the Fat: After cooking, skim any excess fat from the surface for a lighter sauce.
- Adjust Consistency: If the sauce is too thick, stir in a splash of broth or cream. If it’s too thin, let it simmer uncovered in the slow cooker for 15–20 minutes.
- Freeze for Later: This sauce freezes beautifully! Portion it into freezer-safe containers for quick, easy meals.
- Customize the Veggies: Add mushrooms, zucchini, or bell peppers for extra flavor and nutrients.
- Serve Creatively: While pasta is classic, try serving the Bolognese over zucchini noodles, spaghetti squash, or even polenta for a fun twist.
With these tips, you’ll master this Slow Cooker Bolognese and make it your own.
