🥘Ingredient Notes
For this easy oven baked stuffed pepper casserole recipe, you'll need:

- Instant brown rice. I use instant brown rice because it's quicker.
- Ground beef. I use extra lean ground beef to keep this recipe lighter and ww friendly.
- Ketchup. The ketchup adds a lot of flavor to this casserole (I also use it in my Cabbage Rolls).
- Sharp cheddar cheese. I use low-fat cheddar cheese.
*See recipe card for full list of ingredients and quantities
📖 Variations & Substitutions
- Rice: You can use any type of rice you prefer (white rice, cauliflower rice, basmati rice etc) but I use brown instant rice, as it's faster and healthier
- Cheese: I use low-fat sharp/old cheese which reduces the fat and calories and makes no difference in taste. You could also use non-fat cheese.
- Ground meat: you can use lean ground turkey or ground chicken to lighten it up even further and make even more WW friendly!
- Peppers: Use red, orange, or yellow large bell peppers instead of green bell peppers if you truly have a die-hard hater on your hands.
- Spicy: use crushed red pepper flakes to spice it up!

🔪How to Make Weight Watchers Stuffed Pepper Casserole

- Step 1: Brown meat and onion, over medium-high heat, in a large skillet, pot or dutch oven, then drain.

- Step 2: Boil chopped green peppers in water until soft (10-15 minutes). Drain. You could also cook them for about 5 minutes in the microwave. Cook rice in a separate pot. * I use brown instant rice to make it quicker.

- Step 3: Mix cooked rice, green pepper, ground beef, and remaining ingredients (except cheese) together and pour into a prepared baking dish (dutch oven or oven-safe casserole dish).

- Step 4: Top with shredded cheese.

- Step 5: Bake at 350 degrees F/176 degrees C for 12-15 minutes or until cheese is melted. Then turn it up to 500 degrees F and broil for 1-2 minutes until cheese is lightly brown and bubbly. Serve hot . *If you use low-fat cheese, be sure to keep a close eye on it because it burns more quickly than regular cheddar cheese.
🌡️Storage
To store this Cheesy Stuffed Green Pepper Casserole:
- To Make Ahead: Simply make the entire dish in advance, cool it for 15 minutes, then cover it in aluminum foil or plastic wrap (I use Glad press n' seal) and refrigerate or freeze.
- To Store in fridge: Place leftover casserole in an airtight storage container in the refrigerator for up to 4 days.
- To Reheat: You can reheat the casserole in a moderate oven (325- 350 degrees F/165- 175 C) until warmed through (20-30 minutes). You can also rewarm this casserole in the microwave until warmed through (this is what I usually do.)
- To Freeze: Store leftovers in an airtight container in the freezer for up to 3 months. *I do not recommend freezing it if you are using cauliflower rice, as it does not freeze well.
👪 Serving Size
This stuffed pepper casserole recipe makes 10 servings. However, you can half, double, or triple the recipe by clicking on the serving number and selecting the number of servings you'd like. The ingredient quantities will automatically adjust.
🔢WW Points
This Weight Watchers stuffed pepper casserole is 6 WW points. Make it even more WW friendly and low-carb carb you can use Cauliflower Rice. Replace the rice with cauliflower rice. If you're looking for weight watchers casserole recipes, you'll love the delicious flavors in this one!

🍲Dutch ovens
Do you love my cheerful orange casserole dish in the photos? It's actually a DUTCH OVEN. I love that Dutch ovens brown food on the sides when you are cooking on the stovetop and then go straight to the oven. This makes for delicious and simple one-pot casseroles, as well as easy clean-up!
They are made of cast iron, and then coated, so they also retain heat well. They are heavy and last forever. But if you buy a color-coated one (and why wouldn't you?!) just make sure you are very careful with it - the color can chip off pretty easily.
❔Recipe FAQ's
Yes, boiling or microwaving the peppers beforehand ensures they are soft and fully cooked in the final dish.
If you’re not a fan of ketchup, you can substitute it with tomato paste mixed with a little vinegar and sugar or your favorite marinara sauce.
So if you are looking for a healthy, easy, delicious, and Weight Watchers friendly Stuffed Pepper Casserole, then give this one a try!

Nora
Can I use cooked rice?
Terri Gilson
Hi Nora,
Yes, that is what I use -cooked rice. It needs to be cooked before it goes in the casserole. You can use any type of cooked rice you want!
Enjoy…

How important is the ketchup in this recipe? Im wondering if it would still taste good without it, since ketchup isnt all that healthy.
Terri Gilson
Hi Julie,
I'm sure it would still taste good. You can try it without or use less. Or even try making your own healthier homemade ketchup (there's a bunch of recipes online). I really like it with ketchup, as that's how I've always made it. You may need to replace a little of that sweet taste of ketchup with a bit of honey or brown sugar.
Enjoy!

Megan
Did you cook it ahead of time then freeze or dump all of the ingredients in a freezer bag and freeze for a make ahead meal?
Planning freezer meals before baby 🙂
Thank you!!!
Terri Gilson
Hi Megan: Yes, I cook the entire thing ahead, then freeze it in a big plastic tupperware container, defrost, heat and eat. Sometimes I portion it out inot smaller containers for lunches at work. Good luck with baby!
