If you’re not following me on Instagram, you might not know that I’ve been in Sacramento for the past couple of days learning all of the ins and outs of Diamond of California and how their amazing walnuts go from the tree to my kitchen. My husband will tell you that I’m a bit of a workaholic, and there may be something to that claim. Lately though, I’ve realized life is flying by way to fast so I’ve been trying (key word: trying) to take little breaks, celebrate tiny personal victories, and savor the moment a little more.
When I arrived in Sacramento, I had a few hours to waste before I was scheduled to be anywhere. I hadn’t had lunch and a girl’s gotta eat, so naturally I beelined for the nearest Mexican cuisine I could find. It is California after all, they know their Mexican. But this story isn’t actually about the amazing chicken burrito bowl topped with 4 kinds of salsa I ate and nearly cried over. This story is about a girl and her gelato.
After my spi-cay lunch and a good walk around the city I was craving something sweet like it was nobody’s business and found a fancy-pants Italian place right on Capitol Mall called Il Fornaio. Inside this classy restaurant (with a floor-to-ceiling wall devoted to every kind of wine you can imagine) there was a teeny tiny bakery in the corner. As I stood in line, I glanced over the menu and saw mostly sandwiches but I spotted a ginormous chocolate chip cookie in the display case and decided that would definitely satisfy my sweet tooth. But then the lady in front of my walked away with a towering cup of ice cream! What?! That was not on the menu, trust me, I would have noticed. So I asked gal at the counter if they had any gelato. Indeed they did and the flavor of the day was…. Cookies n’ Cream.
It was fate.
I really really really love cookies n’ cream ice cream. And gelato?? Well that’s the cream of the crop as far as ice cream goes. Those Italians, they know what they’re doin’. So there I sat in the middle of downtown sacramento with a double scoop of gelato AND a ginormous king-sized soft-baked chocolate chip cookie. And this is where savoring the moment comes in to play. If I had just stayed at the hotel and worked on my computer all afternoon (and I did consider it, heavily) I wouldn’t have found that Italian restaurant with the teeny tiny bakery with the ginormous chocolate chip cookies and the most amazing gelato known to mankind.
If being less of a workaholic means more ice cream in my life, I’m on board. I mean, why didn’t you lead with that. I would have quit my job years ago.
Now on a less sweet, more savory, but equally delicious Italian note, let’s talk about the meatballs you will every taste, which also happen to be filled with ooey gooey melty mozzarella cheese and are made in a slow cooker. Yes, these are a crockpot wonder my friends. But! If you are short on time or don’t have a slow cooker or whatever, these can also be baked so you have no excuse not to be making, eating, and singing praises for these meatballs. The meatballs alone are wonderfully tasty and seasoned perfectly, but anything filled with cheese is better right?? As a side not, they also freeze very well if you want to make them ahead and bake or slow cook them at a later time!
What people are saying about these Slow Cooker Mozzarella Stuffed Meatballs
“This was so freaking good! I doubled the recipe and used the oven baked method and they came out extremely tender. To my own fault, I should have incorporated the bread crumbs better (had a few bites of highly seasoned crust!) but I’ll remember that for next time and there will be a NEXT TIME! My husband and kids loved them over spaghetti and sauce. Big hit and I can see how they will be great for parties. Even with the cheese seeping out, they still held up together.” – Kimberly
“I tripled the recipe (wanted to save some for the freezer for another meal! :)) , and it was absolutely delicious. I did make the balls about 1/2 the size and still had lots of cheese left over. I made it gluten-free by using crushed Rice Chex instead of bread crumbs.” – Mary
“Made these for dinner tonight with breadcrumbs made from our leftover gluten free bread (hubby is allergic to wheat) and I swear these are the best meatballs I’ve ever had! Thanks for sharing this recipe! Made twelve HUGE meatballs, so with a side of spaghetti, two dinners and two lunches worth 
” – Karen
“I made this for my chris party on Saturday and everyone raved About them and they were gone in a hour! So good im making them for Dinner!!” – Jessie

Slow Cooker Mozzarella Stuffed Meatballs
Ingredients
- 1 pound ground beef
- 1 cup bread crumbs , (panko or regular, Italian seasoned or plain)
- 1 egg
- 1 egg yolk
- 1 teaspoon minced garlic , (or 2 teaspoons garlic powder)
- 1 teaspoon onion powder
- 1 tablespoon Italian seasoning
- 1 teaspoon salt
- ½ teaspoon black pepper
- 3-4 mozzarella cheese sticks , (string cheese)
- marinara or alfredo sauce, for dipping
Instructions
- Chop each cheese stick into half inch pieces (about 6-8 pieces for each cheese stick). Place on a plate and chill in the freezer until ready to use.
- Add ground beef, bread crumbs, egg and egg yolk, garlic, onion powder, Italian seasoning and salt and pepper to a bowl. Mush the ingredients together with your hands until everything comes together.
- Remove cheese from freezer. Scoop out about 4 tablespoons of meat mixture and roll into a ball. Gently push a piece of chilled mozzarella into the middle of the meatball. Roll the ball in your hands to cover the hole where the mozzarella cheese was pushed in. Place inside a greased slow cooker and repeat with remaining meat and cheese.
- When all meatballs are in the slow cooker (*see note for alternate cooking method), cover and cook on high for 1-2 hours or on low 3-4 hours until meat it cooked through (no longer pink). The cheese may start melting out of the meatballs, that’s okay.
- If desired, sprinkle with a bit of fresh chopped parsley or dried Italian seasoning for garnish. Serve with your favorite marinara or alfredo sauce for dipping.

Would you change the cook time if cooking them in sauce I’m the crockpot?
Nutritional information would be nice.
These were a hit at a Traveling Vineyard party I hosted. Only negative comment was tasted like too much italian seasoning. Next time I will lessen the amount. 😊
Have you ever tried cooking these in the marinara sauce instead of dipping the meatballs in it after they’ve cooked? I think I might try doing that! This recipe sounds delicious =)
I have made my meatballs this way for many years. Instead of using the Mozzarella string cheese, I get mozzarella pearls. I always use the oven method. I make homemade sauce and after meatballs are done, I put them all into my sauce and let them cook a bit longer in the sauce. I always get raves on my spaghetti and meatballs!!!
Sounds fantastic, Nancy!
Can you use fresh mozzarella in the middle? JW cuz that’s what I have on hand !
This looks awesome, I cant wait to try it! Is there a way I could cook it in the crock pot longer than 3-4 hours?
I can not wait to try everything I have seen & read just now. I habe not at 7:30am seen anything on here that has made me want to try. Everything you have shared Really looks good . Thank you
I did this but instead of bread crumbs i crushed seasoned croutons … i also added Grape jelly to the bottom of the crock pot and “rolled” the meatballs in grape jelly prior to cooking them. soooo good didnt even need sauce!
I love using my crockpot when the Texas weather heats up. I never made meatballs from scratch and decided to give this a try. We decided to have meatball hoagies using a marinara sauce and topping with additional cheese. Our son said this was a keeper. Thank you for making the recipes easy to follow!
I love the idea of this but they were in the crock pot on low for 3 hours or so (we have a quick crock pot). The balls were burning and cheese was melting out. When I went to cut them the balls were very firm but they looked pink inside. I then put them in water on the stove and cooked them for at least 10 minutes and they continued to be pink inside. It was really strange. I just don’t see how they still can’t be cooked?
