 Step by Step Instructions for Making Cheddar Bay Spaghetti Casserole

 STEP 1: 

To make this biscuit and spaghetti casserole I started by cooking some spaghetti until almost tender. 

Then I drained the pasta and set it aside.

 STEP 2: 

While the spaghetti was cooking, I dropped some lean ground beef into a large skillet over medium-high heat.

I crumbled the ground beef well.

 STEP 3: 

I added some diced onions to the skillet.

I stirred well and continued cooking until the ground beef was fully browned.

 STEP 4: 

I added some chopped garlic to the skillet.

I stirred well and continued cooking for about two minutes.

 STEP 5: 

I added some salt and pepper.

I stirred well again.

 STEP 6: 

I added a jar of marinara sauce to the skillet.

I stirred the ground beef and marinara together.

 STEP 7: 

I added the cooked spaghetti to the skillet.

I stirred until all of the noodles were coated in sauce.

 STEP 8: 

I sprayed a 9 x 13 inch baking dish with cooking spray.

I scooped about half of the spaghetti mixture into the baking dish and spread it out evenly.

 STEP 9: 

I dumped a tub of ricotta into a mixing bowl.

I also added some milk and Italian seasoning to the bowl.

I stirred the ingredients until well combined.

 STEP 10: 

I poured the ricotta mixture over the spaghetti in the baking dish and spread it out evenly.

I sprinkled some shredded mozzarella cheese over the ricotta.

 STEP 11: 

I spooned the remainder of the spaghetti mixture over the cheese.

 STEP 12: 

I poured a box of Cheddar Bay biscuit mix into a mixing bowl and set the seasoning packet aside.

I added some shredded cheddar cheese to the bowl.

I also added some milk to the bowl.

I stirred until no large lumps remained.

 STEP 13: 

I poured the biscuit batter mixture evenly over the spaghetti in the baking dish.

 STEP 14: 

I placed the dish in the oven and baked the casserole until the biscuit topping was nicely browned.

 STEP 15: 

Then I removed the dish from the oven and placed some butter in a microwave safe bowl.

I melted the butter in the microwave.

I added the packet of biscuit seasoning mix to the melted butter.

I stirred the seasoning and butter together well.

 STEP 16: 

I brushed the butter mixture over the biscuit topping on the casserole.

I left the casserole to rest for about five minutes to give the biscuit time to soak up the butter.

Then the hearty spaghetti casserole was ready to scoop and serve.

Every bite of this casserole is loaded with rich, cheesy pasta and fluffy, savory biscuits baked to perfection.

The cheesy, garlicky biscuits soak up just enough of the rich tomato sauce, making them unbelievably soft inside with a crispy, golden top.

It’s a guaranteed crowd-pleaser, whether you’re feeding your family, meal prepping, or bringing it to a potluck.
