It was not fancy fru-fru dinner day. It was ‘put some stuff in the crockpot’ day. I like those days. No stress-cooking days. Sometimes I need those days. Don’t get me wrong, though. It doesn’t mean ‘no flavor’ day. This slow cooker ravioli casserole really hit the spot. It’s pretty straightforward to make, but the flavors make you feel like you spent hours at the stove. The key is to not add anything to your slow cooker that doesn’t add flavor. And this has the flavor! And tons of ooey-gooey melty delicious cheese!
Make It Yummier
This slow cooker ravioli casserole gets better with better ingredients. I used flavorful, fresh Italian sausage. I found a good cheese ravioli in the frozen section of my grocery store. And I used fire-roasted tomatoes (they add great flavor and texture). And importantly, I used freshly shredded and freshly grated cheeses. Those make a huge difference. I used to use bagged shredded cheese out of convenience. But freshly-shredded cheese melts so much better. So much creamier. And blocks of cheese are almost always cheaper than that pre-shredded stuff.
Like a little heat? Add a pinch or two of dried red pepper flake to the meat mixture. Or (and!) use spicy Italian sausage. This dish won’t be crazy hot but it’ll have a nice warm-you-up kind of heat.
Serve with more freshly-grated parmesan at the table. A good sprinkling or two of more cheese really adds a nice finishing touch (and flavor) to this dish!
Don’t let the ravioli over cook in the slow cooker. Pasta tends to get thick and rather, well, gloppy if it spends too much time in the heat. If that happens to you, add more marinara sauce to thin it up a bit.
Reheating
You can reheat the ravioli in the oven or stovetop. I recommend the oven. Either way I’ll add a bit more marinara so it doesn’t dry it. I’ve found that reheating on the stovetop doesn’t treat the ravioli as well. It’ll still be good, but it’s hard to get it heated through evenly.
