Cheesy Tomato Biscuit Casserole

I don’t know about you but I get in such a rut with side dishes. Most of the time it’s because I’m feeling uninspired or lazy and the same old same old is easy to throw together. I’m happy to report that I branched out this weekend and now I have a new, amazing side dish to add to my repertoire. And, bonus, it reheats well (if you have any leftovers that is).

My friend Amy posted this Cheesy Tomato Biscuit Casserole months ago, but I’ve been waiting until the height of tomato season to make it. While you can get tomatoes year-round, the ones we’re enjoying right now are insane. I don’t know if it’s just a good year for tomatoes or what, but damn. I feel like I need to eat. all. the. tomatoes. every. day. So, so good.

As I was typing up this post I realized I forgot the onion in the original recipe. Oops! Since we thought it was amazing without it – and, bonus, if you skip that step you have one less pan to clean – I’m leaving it out. I also opted to add fresh chopped basil once this came out of the oven, mainly because my basil plant is out of control right now and because tomatoes and basil are so good together. Totally your call. Also, use way more tomato than you think you need. Tomatoes have a lot of water in them so they’ll shrink as they cook.

Hurry up and make this simple and delicious side dish now. You won’t be sorry!

Cheesy Tomato Biscuit Casserole
Slightly modified from BellyFull

1/2 cup sour cream
1/4 cup mayonnaise
1 cup shredded cheddar cheese
1/4 teaspoon kosher salt
1/4 teaspoon pepper
1/4 teaspoon dried oregano
1/4 teaspoon garlic powder
1 container (16 ounce) Pillsbury Grands Buttermilk Biscuits
4 tomatoes, cut into 1/4-inch slices
paprika
fresh basil, chopped (optional)

Preheat the oven to 400 degrees. Coat a 9×13 casserole dish with nonstick cooking spray.

Combine the sour cream, mayonnaise, cheese, salt, pepper, oregano and garlic powder in a small bowl. Set aside.

Press the biscuits into the casserole dish, pinching the seams together so they cover the bottom of the pan and pushing the dough slightly up the sides. The dough will be thin.

Arrange the tomato slices on top of the biscuits, overlapping to fit as many slices as you can. Spread the cheese mixture over the top then sprinkle with a little paprika.

Bake for 25-27 minutes until the dough is cooked through and the cheese mixture is browning and bubbly. Let stand for 10 minutes, then top with chopped basil and cut into slices.

To reheat leftovers: Preheat a toaster oven to 350 degrees. Spray some foil with non-stick cooking spray and place a slice of the casserole on top. Heat in the toaster oven, being careful not to burn the edges of the crust, for about 5-10 minutes depending on your toaster.
