Spaghetti Slow Cooker Meal Prep

Spaghetti is a fan favorite in my household.  I have been making this recipe almost weekly for years.  You can make it in the crockpot or on the stovetop.  Last year, I decided to start meal prepping so I had something ready to go for workday lunches or for dinner on busy nights.

  • 1-2 lbs lean ground beef or turkey or sausage
  • 1 bell pepper
  • 1 yellow onion
  • 4 cloves garlic
  • 1 jar of spaghetti sauce
  • 1 can of diced tomatoes
  • 1 small can tomato paste
  • 1 tsp dried basil or fresh
  • 1 tsp dried oregano
  • 1 tsp dried parsley or fresh
  • 1 tsp ground black pepper

Optional veggies to add:

  • as much kale or spinach as you like
  • zucchini
  • mushrooms
  • red, yellow or orange bell peppers
  • more garlic (we love garlic)
  • red pepper flakes


  1. Chop all the vegetables.
  2. Add all ingredients to the slow cooker. I use liners to make the cleanup easier.
  3. Thoroughly mix together.  Use a wooden spoon and be sure to break up the meat well, so that there are not any large chunks.
  4. If using sausages like I did this time, lay them on top of the mixture.
  5. Cook on high for 4 hours or low for 7+ hours.
  6. Serve with your favorite pasta or I often use my spiralizer and eat with zoodles – zucchini noodles.
  7. Another variation is to add frozen meatballs in the last hour.
  8. You can also cook the sauce in a large stock pot, start with browning the meat and add the veggies, spices, then tomato sauce. Simmer 1-2 hours covered.

I like to serve pasta with fresh basil, parmesan and red pepper flakes.

I bought my first package of these $9 meal prep containers from Walmart last August.  The containers are quite durable – they held up the entire school year and are freezer, dishwasher and microwave safe.

I have started my back to school meal prepping.  This is a variation on the recipe I shared above.  I used rigatoni and added a few tablespoons of cream cheese to make the sauce creamy.

I have been prepping and stocking my freezer for when I return to work.  It is so convenient and helps reduce my stress when I know I can grab one of these on the way to work and microwave it for lunch or when the kids have sports in the evenings we have dinner ready to go.  Stay tuned, I will be sharing my fajita bowls and stir-fry meal prep recipes!

  1. Do you need to brown the meat before putting it in the crockpot?

    1. No need to brown, you can if you’d like.
