Ingredients

  • 1 can refrigerator biscuits (Pillsbury Big Country biscuits)
  • 1 1/2 cups milk
  • 1 (9 1/4 oz.) can tuna
  • 2 (10 oz.) cans Cheddar cheese soup
  • 2 tablespoons minced onion
  • 2 cups frozen peas

Instructions

  1. Arrange the biscuits in an ungreased 9 x 13-inch pan.
  2. Combine milk, tuna, cheese soup, minced onion, and frozen peas in a bowl.
  3. Pour the mixture over the biscuits in the pan.
  4. Bake at 400°F (200°C) for 25 to 30 minutes until biscuits are browned and puffy, and the top is coming up through the tuna mix.

Tips & Substitutions

For a creamier texture, consider adding a cup of sour cream or Greek yogurt to the mixture. If you're short on time, you can use canned peas instead of frozen. Experiment with different types of cheese soup, like broccoli cheese, for a unique twist. You can also add cooked shrimp or crab for a seafood variation, incorporating flavors similar to those found in classic Seafood recipes.

Serving Suggestions

This casserole is hearty enough to serve on its own but pairs beautifully with a simple green salad or crusty bread for a complete meal. For a more substantial side, consider serving it alongside Creamed Salmon. A light dessert, like fresh fruit or sorbet, can round out the meal nicely.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to three days. To reheat, place individual portions in the microwave, or bake in a preheated oven at 350°F (175°C) until heated through, about 15-20 minutes. Adding a splash of milk can help restore moisture during reheating.

Frequently Asked Questions

Can I use a different type of protein instead of tuna?

Absolutely! You can substitute the tuna with shredded chicken or even some cooked minced lobster for a gourmet touch. Just make sure to adjust the cooking time if you're using raw proteins to ensure they are fully cooked through.

What can I use instead of refrigerator biscuits?

If you prefer a homemade option, you can make your own biscuit dough or use puff pastry for a flakier texture. Alternatively, a crust made from crushed crackers or breadcrumbs can provide a different base that still complements the casserole well.

Is there a way to make this dish healthier?

Yes! You can use low-fat cheese soup and skim milk to reduce calories. Adding more vegetables, such as bell peppers or spinach, boosts the nutritional value without sacrificing flavor. You can also use whole grain biscuits for added fiber.
