Ingredient List

For the Sauce:

• 2 carrots, peeled and diced
• 2 celery stalks, diced
• 4 garlic cloves, minced
• 1 can (28 oz) crushed tomatoes

Ingredient Notes

• I always use San Marzano crushed tomatoes for this—it adds so much natural sweetness and depth.
• Don’t skip the tomato paste! It makes the sauce rich and thick without extra simmering.
• Red wine is optional, but I love the extra layer of flavor it gives. A dry red like Chianti or Cabernet works perfectly.
• Milk or cream at the end makes it silky and balances the acidity of the tomatoes—totally worth it.
• Fresh basil on top just brightens everything up; I never leave it out.

• Wooden Spoon or Silicone Spatula – For stirring the sauce without scratching your slow cooker.
• Measuring Cups & Spoons – To keep your seasonings and liquids just right.
• Colander – For draining your pasta. I like a large, sturdy colander that fits in my sink.

Instructions

1. Prep the Vegetables

• Peel and finely dice the carrots and celery.
• Chop the onion and mince the garlic cloves.
• Pro Tip: Keeping the veggies uniform in size ensures even cooking and a smoother sauce texture.

2. Brown the Meat (Optional but Recommended)

• In a large skillet over medium heat, cook the ground beef or turkey until no pink remains.
• Break it into small crumbles with a wooden spoon.
• Drain excess fat if needed.
• Pro Tip: Browning the meat first adds extra flavor and depth to your slow cooker bolognese sauce.

• Pro Tip: Give everything a good stir to evenly distribute the flavors before cooking.

4. Slow Cook the Sauce

• Give it a stir halfway through if possible.
• Pro Tip: The longer it cooks on low, the more tender the meat and deeper the flavor.

Tips and Tricks for Success

• Use fresh veggies whenever possible – Fresh carrots, celery, and onions give a brighter, sweeter flavor than frozen.
• Don’t rush the cooking – Low and slow is key; it brings out the best flavor in your slow cooker bolognese sauce.
• Taste and adjust – About 30 minutes before serving, taste and tweak seasoning with salt, pepper, or herbs.
• Stir occasionally if you can – Helps prevent sticking on the edges and ensures even cooking.
• Make extra for leftovers – This sauce tastes even better the next day and freezes beautifully.

Ingredient Substitutions and Variations

• Meat options – Swap ground beef for ground turkey, chicken, or even a mix of beef and pork for a richer taste.
